Indeed, and someone could write an "NFS file name handler" so you could use something like "/nfs:/...". 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.
