The following are quotes from the DRMOS Patent itself:
-------------
The Content Provider (ISP) must maintain a registry of "subscriber
computers". This is the SPA and Central Licensing:
Therefore, the content provider would have to maintain a registry
of each subscriber's DRMOS identity or delegate that function to a
trusted third party. ... Because the basic DRMOS and additional
components always have the same identities when executing on a
specific type of processor, the content provider has only to maintain
a list of the identities for the combinations of the basic DRMOS and
additional components that the provider trusts. Each identity uploaded
is then checked against the list.
------------
Soon, changing your PC's system clock could become illegal:
This alternate embodiment requires a secure time source to be
available on the subscriber computer so the user cannot simply
turn back the system clock on the subscriber computer.
------------
Pay-per-use operating system and components:
As described above, components may be valid only until a specified date
and time, and content may also be licensed only until a certain date and time.
The monotonic counter described earlier can also be used to ensure that the
computer's clock cannot be set backwards to allow the replacement of a
trusted component by an earlier, now untrusted version.

Stallman is right again, DEBUGGING IS NOW ILLEGAL, enforced under Section
1201 of H.R. 2281 (The DMCA):
DRMOS Patent:
An example of one kind of procedure that must be prohibited is loading a
kernel debugger because it would allow the user to make a copy of the
content loaded in memory. If the user of the subscriber computer attempts
to load a kernel debugger into memory, the DRMOS can either 1) refuse
to load the debugger, or 2) renounce its trusted identity and terminate
the trusted application that was accessing the content before loading
the debugger. In the latter case, the memory must also be purged of the
content before the debugger is loaded.
See The Right to Read, Stallman:
There were ways, of course, to get around the SPA and Central Licensing.
They were themselves illegal. Dan had had a classmate in software,
Frank Martucci, who had obtained an illicit debugging tool, and used
it to skip over the copyright monitor code when reading books. But he had
told too many friends about it, and one of them turned him in to the SPA
for a reward (students deep in debt were easily tempted into betrayal).
In 2047, Frank was in prison, not for pirate reading, but for possessing
a debugger.
Dan would later learn that there was a time when anyone could have debugging
tools. There were even free debugging tools available on CD or downloadable
over the net. But ordinary users started using them to bypass copyright
monitors, and eventually a judge ruled that this had become their principal
use in actual practice. This meant they were illegal; the debuggers' developers
were sent to prison.
-------------
You can no longer delete specific data from your hard drive:
DRMOS Patent:
For example, the DRMOS can allow the user to delete an entire content file but
not a portion of it. Another example is that the DRMOS can allow the user to
terminate all the threads of execution for a trusted application but not just
a single thread.
-------------
Again, debuggers are not permitted:
DRMOS Patent:
Finally, a DRMOS must protect the trusted application itself from tampering.
The DRMOS must not allow other processes to attach to the process executing
the trusted application. When the trusted application is loaded into memory,
the DRMOS must prevent any other process from reading from, or writing to,
the sections of memory allocated to the trusted application without the explicit
permission or cooperation of the trusted application.
-------------
Users may not share data:
DRMOS Patent:
Such a facility is used when downloaded content can be accessed only by a particular user. Moreover, if downloaded content is to be accessed only by a
particular user and by a particular application, the secret to be stored may be divided into parts, with one part protected by an application-specific key
and the other part protected by a user-specific key.
Applied to Stallman's Right to Read. Bear in mind these are e-books and sharing
would be a form of copyright circumvention:
He had to help her--but if he lent her his computer, she might read his books.
Aside from the fact that you could go to prison for many years for letting
someone else read your books, the very idea shocked him at first. Like
everyone, he had been taught since elementary school that sharing books was
nasty and wrong--something that only pirates would do.
--------------
The "Key Vault" and trusted third party (Central Authority):
DRMOS Patent:
Once the data is encrypted using the storage keys, there must be a way to
recover the keys when the DRMOS identity changes (as when the operating system
is upgraded to an incompatible version or an unrelated operating system is
installed) or the computer hardware fails. In the exemplary embodiments
described here, the keys are stored off-site in a "key vault" provided by a
trusted third party. In one embodiment, the DRMOS contains the IP addresses
of the key vault providers and the user decides which to use. In another
embodiment, the content provider designates a specific key vault and the DRMOS
enforces the designation. In either embodiment, when the user requests the
restoration of the storage keys, the key vault provider must perform a certain
amount of validation before performing the download.
-------------
Your computer cannot be used to copy content:
For example, one property might be that the application cannot be used to copy content. Another example of a property is one that specifies that the
application can be used to copy content, but only in analog form at 480P resolution. Yet another example of a property is one that specifies that the
application can be used to copy content, but only if explicitly allowed by an accompanying license.
-------------
Looks like the MPAA has been engaged in some Retail Politics:
In one embodiment, the access predicate takes the form of a required properties
access control list (ACL) as shown in FIG. 10. The required properties ACL 1000
contains a basic trust level field 1001, which specifies the minimum rights
management functions that must be provided by any application wishing to process
the content. These minimum functions can be established by a trade association,
such as the MPAA (Motion Picture Association of America), or by the DRMOS
vendor.
-------------
More Pay-per-view OS functions:
As described briefly above, the license data structure 1100 can limit the number
of times the content can be accessed (usage counter 1101), determine what use
can be made of the content (derivation rights 1103), such as extracting still
shots from a video, or building an endless loop recording from an audio file,
or a time-based expiration counter 1105.
-------------
Pay-per-listen feature:
The sublicense rights 1107 can impose more restrictive rights on re-distributed
content than those specified in a license for content downloaded directly from
the original content provider. For example, the license 1100 on a song purchased
directly from the music publisher can permit a song to be freely re-played while
the sublicense rights 1107 require a limit on the number of times the same song
can be re-played when redistributed.
