Apollo's NFS will not allow you to run an Apollo binary from an NFS disk. Also,
although the compilers can read source from an NFS disk, they cannot write to
an NFS disk - they must write to an Apollo filesystem.  Apollo cites the reason 
for this as being that their file system is a single level store allowing for 
the direct mapping of binaries into address space instead of a page area.  The 
glitch in this reasoning is that Sun can do this with NFS.

*Sigh* - wouldn't it have been nice it Apollo had made DOMAIN public domain
before NFS came along ? :-)
