Plus, I can't put a linux machine on the campus network, they register everything by MAC, and make me take it down to the tech's to get it checked out. They are afraid of "linux spreading virii on their network." Umm...Yeah.....

you are seriously dealing with some dumb tech people at your school(or the there just saying that for another reason) But just go and get you a router and only thing they will see is the router's hardware address and you will then be fine!
