They won't have any choice, if Alistair Banks' statements are correct.  In
order for Win32 or NT or whatever it is called to get B2-level certification,
"The TCB shall maintain a domain for its own execution that protects it from
external interference or tampering ... Features in hardware, such as 
segmentation, shall be used to support logically distinct storage objects
with separate attributes (namely: readable, writeable)." (from DOD 5200.28-STD,
3.2.3.1.1 System Architecture).  Now that we have the official mumbo-jumbo,
does anybody out there who is familiar with the Orange Book care to comment 
on how useful a B2 rating will be on the limited set of functions that will
be supported by NT?  Is it going to prevent downgrades via the clipboard?
Enforce security labels on printed output?

Just curious.
