FYI, I've often found that tunneling CVS over SSH is substantially faster
than NFS.  This appears to be a property of CVS doing some sort of
explicit pipelining, whereas with NFS, it spends a lot of time blocked on
synchronous stat() operations against the CVS repository.  Of course, last
time I used CVS over NFS seriously was on 10mbps ethernet, so this well be
a non-event with gigabit.  :-)  Setting up the SSH connection is slightly
more expensive, but the reduced apparent latency makes a big difference.
