Classic example of
FUD at work. FUD is actually the entertainment industry's most successful weapon thus far against illegal file sharing, and you should probably read
this page. As for speaking to the people who run your school about this, it will most likely be a complete waste of time - they don't really care about their students (at least not those in administrative positions, trust me, I teach at the University of North Florida and they are all elitist politically correct cutthroat drones). I suggest you get your own network (I assume you're currently accessing the net from a proprietary network owned by the school, who leases the access to the net from their ISP), and pay for your own ISP service. This means that your internet activity can't be monitored by the school, and if it were, you could actually sue them for breaking privacy laws and any evidence that came from their spying would be tainted and unusable in court.
