NFSv4 has a completly different logic then NFSv3 -- the server keep a "current
filehandle" that is not retrieved by the client, if I recall correctly -- but
is still based on ONC RPC, so a part of the work from my GSoC could be reused.

However full NFSv4.1 support would be a bit more difficult to implement
properly especially when referals and replicas are involved.

If someone is willing to implement it, I'll happily explain how my code works
if it is necessary. :)
