I might object to the characterization of "cleanly".  We would need system
calls which matched the specific semantics of NFS operations.  For example,
we would need system calls which understood pre-operations and 
post-operation
attributes.  We would need system calls which understood 32 bit limits so
that we could correctly implement NFS version 2.  NFS version 3 and NFS
version 2 are probably close enough that we could use a common set of
system calls with appropriate flags, but it does not seem likely that these
system calls would suffice for NFS version 4.  We could end up with a whole
lot of system calls, even if they all went through a common entry point into
the kernel.

    Thanx...
