It seems to me there are some big potential dangers to a Cygwin UMSDOS
implementation. The main issue is that UMSDOS expects that it is the only
thing that will be modifying anything in a synchronized directory while it
is mounted. I don't think this can conceivably be enforced inside a
running Windows session short of holding locks on every single file.
That brings me back to the more limited, but vastly simpler idea of adding
a feature to cvs that allows producing a script of chmod commands during
check-out that reflects the proper file permissions. I might even attempt
this myself after re-learning such things as how a make file works since I
haven't done C programming in about 12 years now.

Implementing UMSDOS could be done two ways (there may be others)
1) cygwin directly translating the UMSDOS information and making it
available to cygwin programs.
2) a IFS driver that can translate UMSDOS into the win32 namespace.
Now 1) shouldn't be too hard. But 2) while a lot harder, would have
significant benefits... NFS drivers etc would be technically similar to
write :}
However I don't have AU$6000.00 hanging around to buy the MS DDK for a
hobby. And there is no full opensource DDK for win32 at the moment. A
project to develop such a thing could probably piggy back on ReactOS,
which is coming along at a great rate of knots (they have TCP/IP now).
