Maybe it's time for the SeqFan community
to start looking around for some sort of
"collaboration architecture" to distribute
the workload.  I have been hearing about
a number of these lately, but haven't yet
picked up on them enough to try them out --
here is just the most recent blurb I got,
on a system called "Croquet":
