From a practical standpoint, it can't be done.

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.
