Lot and lots of HD space needed.

(NTFS)
CD Shell (formerly BootScriptor) should work.
CDImage works good for DVD's. (2.47)
AutoPlay Media Studio for GUI work. (4.0.0.3)
I have started a DVD to test this already.
It Has Windows XP Eval,Gold,SP1,SP1a all versions. (Home,Pro,VLK)
Waiting on SP2 now. The Win PE's,SP's,Boot floppys ect. too.
Few misc. tools. So far its 6+GIG before CDImage and 1.4 GIG after.
I plan on putting Win2003 on this DVD also.
The real work is going to be setting up CD Shell and the GUI.
I have a bud @ work that has a burnner. So I'll have to RAR and burn
reg. CD's.
