In principle, options ought to include:

- OpenAFS
- 9P (from Plan 9)
- Coda
- Intermezzo

Some of those are pretty heavy on administrative overhead; none are as easy as:
On server
  echo "/path/to/export 192.168.0.22(rw,async)" >> /etc/exports
  SIGHUP nfs server process

On client
  echo "server:/path/to/export /path/to/mount nfs" >> /etc/fstab
