I'll see if I can try a few experiments in the office (might be a few days before I'm there for long enough, since I do on-site networking most days). I've had pretty good luck there using knoppix on the network so far.

I haven't really tried multi-user printer setup under knoppix, yet, since where there's at least one PC for everyone there. I generally just set up a printer for use under my own user name and do everything from there.
