1. There are no streams under Xenix, it is all spoofed by the streams
   library.

2. There is no rpc support for Xenix.

3. The TCP/IP is about as solid as the Iraqi military.

There is supposedly an NFS product for Xenix called Fusion from Network
Research, but I am only aware of its existance, nothing more.

Your customers best bet would be to chuck Xenix for one of the System V/386
Release 3.2 or 4.0 products (i.e. ESIX, ISC, Dell, MicroPort, UHC, or SCO)
that already support NFS.

If someone can and has proven me wrong, please speak up.  I was looking for
such a product a long time ago.  But to my understand, Xenix does not
have the necessary kernel support to handle rpc.pcnfsd even with the streams
and TCP/IP packages added.
