My efforts in this regard keep getting pushed back due to too many
other things flying around, but I've been told that Sun Cluster
*should* respect full local filesystem semantics.  How close to
reality that is, I have not been able to confirm.  I'm hoping we
might be able to do some experimenting later this term, but then
I've been saying that for a while.  Sigh.
