Well, sure it's possible on most NFS implementations where the network
supports SLIP, but it's not very pleasant.  Be sure that UDP checksumming
is turned on in your kernel (for most BSD-derived systems, that means the
variable 'udpcksum' should be set to 1.)  Because the SLIP link level has
no checksum, line noise can easily corrupt a packet (and over an NFS mount,
corrupt your files.)  I'd also adjust your rsize and wsize mount parameters
to something smallish.

I have a 19.2kb SLIP line as my connection to the Internet, and have
occasionally mounted file systems located several gateways away.
It works.  I don't use it routinely for read/write work.  I find it
most useful for mounting read-only filesystems which have files I
occasionally refer to by name (Athena's 'xpix' bitmap locker, etc.)
