[OpenAFS] Userland NFS-AFS translator?

Nobody (yet) has written a user-land AFS-NFS translator.
Theoretically it could be done using the user-land AFS cache provided
by OpenAFS.  As for System2/System3 backup, you can only replicate
read-only data.  But yes, you would achieve failover in the case of a
server failure.
