Indeed, and someone could write an "NFS file name handler" so you could
use something like "/nfs:<host>/...".  It might even be reasonably easy
for Tramp to provide that (since I believe GVFS supports NFS access).
But it won't help when Emacs accesses to NFS files via normal OS calls
rather than via Tramp.
