I used to do this routinely (about 4 years ago at least now) using
an rpc-over-ssh program which I've just forgotten the name of. Anyhow
it allowed you to route all RPC traffic over a port-forwarded ssh
connection, and was a useful way to make NFS somewhat secure over the
Internet at large. Mail me if you can't google it.
