FWIW, you actually get marginally better performance with a hub than you do
with a switch if you have fewer than about 10 PC's.  With few hosts, the
switching actually slows things down.  We tested it back when I was working
as a DBA because we would often stick our application server and database
server on an isolated LAN with each other to handle the data query traffic,
and a hub was always faster when there were only a couple of systems on it.

My $0.02.

Really, for adequate performance, we need a switched environment...
My suggestion for what to do with the cluster: Come up with an
algorithm/matrix for determining how long it would take a thousand
monkeys pounding on typewriters to synchronously type "the entire works
of Shakespeare", write a proposal for a federal grant, test it on the
Linux cluster, and use the proceeds to benefit some of the other
worthwhile projects we have previously discussed.  (Don't laugh--I heard
that someone recently got a grant to study how mermaids would procreate
if they existed)...
You gonna be at the meeting tomorrow night?
