I seem to remember Hans Reiser making a credible suggestion years ago when NFSv4 was still in draft. It didn't fly, but I don't really remember why.
The NFS server gets to either return a cookie like it currently does, or sets a flag (or maybe returns a special cookie) which says 'just use the name'. A READDIR request contains either a cookie or a filename. Either mean "This identifies the last name I got from you, give me the next one".
Is there something that makes that interface problematic?
