NFS is an RPC based protocol.  The first step is to be able to do
SunRCP/ONCRPC. Python has an 'xdrlib' which is how parameters are
marshalled, unmarshalled in sunrpc.  If allowed under "from scratch", you
could wrap the C rpc lib for python - they handle retries and other low
level stuff.  You could look "Remote Tea" for Java, and translate to
python to get a pure python oncrpc lib.  Or you could look for such a
package already written (a quick search didn't reveal any).

Once you have rpc, then it is "just" a matter of having your python server
implement the set of calls specified for NFS.  BTW, apparently python was
used for quickly building test rigs while developing NFS v4.

Having a framework for python NFS server could be useful - think custom
filesystem.  Although a python binding for fuse + C NFS server would
be more general (use locally as well as remotely).
