    Believe it or not (I couldn't the first time I read it), PC-NFS 3.0 from
    SUN does have drivers to run NFS over Dialup SLIP.  The manual says it
    can be done, but its on the to-do list here, so I don't know if it
    actually works.  Good luck.  Please write back if you get it to run!
    
I've used Interdrive (our NFS client) over SLIP, and I've also used dial-up
SLIP (but not NFS over dial-up SLIP).  If I were using NFS over dial-up
SLIP, I'd make sure that both ends were sending (and checking) UDP
checksums.  Interdrive does this; I don't know about PC-NFS or BW-NFS.
Enabling UDP checksums can require source or special object modules on some
hosts (Sun & Solbourne at least), or can be as simple as patching a single
location in the kernel (Ultrix, Encore, others).

If my experience is any guide, the PC will be simple to configure, and
everything will work fine once you figure out the proper magic invocations
on the host.  Of course, this last may be hard to do - I still don't know
why 'slattach' rejects one of our dialups because it can't do the 'set line
discipline' ioctl().  Such is life in the innards of Unix...
