Thanks, but this is already my fallback.  I could also simply not serve 
NFSv4 from the server if I really decide to abandon NFSv4.

I was hoping, though, to be able to switch to NFS4 at some point for a 
couple of reasons: the improved (perhaps?) ACL semantics and the single 
"port of entry" simplicity for firewalling.

I lock down the various ports needed, rather than letting them float, so 
NFSv3 can be firewalled successfully.  Simpler is better, though, so I 
was hoping that I'd be able to drop this.

What serious problems does NFSv4 have?  Is it just the issue with mixed/
independent databases of users with which I've been struggling, or is 
there more?

Thanks...
