I think a few low cost routers are thw way to go. You could go crazy and 
make each staircase (group of ~20 students) a different subnet. Build a 
few router boxes which each then uplink to the switch. As they're on 
seperate cables, and logically separate networks you should be able to 
at least limit the infection in lots of different ways.

I guess each router should connect to (number of avail. PCI slots - 1) 
staircase groups. The last PCI slot is for the uplink to the switch for 
the building. Each router should have a default route, as well as the 
route to each of the other subnets in the building. You can stop and 
isolate traffic using these routers and pretty standard firewall steups 
as you see fit. Shouldn't be too expensive either as the harware is all 
commodity stuff. I suppose you choose the boxes for the routers based on 
lowest cost per PCI slot.

My 2p.
