Someone else suggested NFS privately.

I think you're confusing NFS the wire protocol with certain
implementations of it.  Some *implementations* map UID 0 to something
else; this is orthogonal to the *wire protocol*.

(Hmmm.  If your super-user isn't UID 0, you will find that other
implementations of NFS will likely map your UID 0 but not your
super-user; this can be good or it can be bad...and thus it can be an
example of an interoperability problem, even though it isn't really an
answer to the question about wire protocols.  Good point.)
