On that note, has anybody used a Mosix cluster? What results are you seeing. I run a few machines full time at home for various tasks that need to be kept separate (i.e. different gateways to the internet) and I was wondering if I could set up a Mosix cluster to supplement my wife's box (running Slack 8) by having it use the cluster to speed up processes that spawn many sub-processes. Anybody doing something like this at work or home? Think it could be some fun to try. (Of course this may bend some peoples definition of fun!)
