Ok. Me back again with two new wishes. I will mention my first two wishes anyway.
1. different resolution setting for each user
2. once we disable the Shutdown for a particular user, the Shutdown cannot be displayed for him, not at least in the Welcome Screen. I hope this would happen in the next O/S -- this can be done in Local Security Policy
3. schedule options to connect/disconnect in dial up network connections
4. ability for more than one user to log on to a single computer via network -- this is getting true in Windows XP SP2!
5. ability to present a report of what programs each user was running before the last BSOD
