Thanks for the suggestions.

Any advice on how to do some of this traffic shaping? The student network is handled separately from the rest of the building, so we can get extreme on the solutions. Currently, there's just a WRT54GL running Tomato. I've attempted to set up QoS as best I can, but I've not had any experience doing that, so I really don't know what I'm doing with it. Through QoS, I've tried throttling P2P traffic, and I've limited the upstream bandwidth to around 1400Kbps.

Would you guys recommend another piece of hardware, or can I get away with what I have? That would be ideal, because as I implied, these folks don't want to spend a whole lot.
