What goes on in companies in the evenings? Or in small or home office installations ( Fred in his shed, with 4 or 5 computers, ) after dark and when they're not holding blood rituals to KAYSL? ...
Well, the chances are they're gonna keep their servers running ... I know I do. So how about a client for clusters? - rather than keeping separate installations on individual machines and accounts.
A cluster client downloads an ULTRA-LARGE folding simulation ... and farms bits of it out to the cluster it's attached to? That way ... all those little older machines, or heavily used machine ( that normally can't complete by the deadline ... the 100ppd devices) can contribute their few extra folds to a larger project. The folder could sit happily in the knowledge that they're draining the last few point out out every digital device they own.
Sorry ... I'm just wibbling ... I think I've got "Post Folding Stress Syndrome" ... I'm getting flashbacks of Helicopters, Napalm, a very young Martin Sheen in the Russian poppy fields ~8^S

The main problem of a cluster client would be data exchanges ... I don't know if you looked at the amount of data exchanged by SMP client (monitor localhost), but it's quite important, and would become an issue very fast, unless you use very expensive > 1 Gbps network connections 
... and when FAH is not compute limited, it doesn't do very well (example : A1 SMP core).

It might be worthwhile if you were directly connecting two servers via a 1Gb Cat5e/Cat6 crossover cable - keeping latency to a minimum while maximizing throughput by removing any switch or router.
It has to be crossover though! To tell, look at both connectors - on one end the wire colors should be in the order: White-orange, orange, white-green, blue, white-blue, green, white-brown, brown. The otherend is ordered: White-green, green, white-orange, blue, white-blue, orange, white-brown, brown.
You could also use crossover cables to connect multiple computers in a token ring, or star mesh topology - provided that each unit has at least two ethernet ports.
(You can recite all kinds of crap after you take a couple Cisco classes)
I was planning on doing something similar, but with Linpack. I can post the results here as I go along, if anyone's interested.

So how did it go?
