Enable Bittorrent at the University Level?

Sorthum writes: "I'm a network administrator for a small university (approximately 5000 students all told). We're running NAT in the dorms, which obviously restricts BitTorrent traffic. We do an annual student survey, on which "Residental Network" is listed as the number 2 complaint. This translates more or less into "Bittorrent is slow here." My boss is in a frenzy to appease the users at virtually any cost, but it seems to me from my research that the only real way to improve Bittorrent speeds is to start assigning public IPs to the dorms. Add to that the potential liability of making a service that by most reports has upwards of 90% of its traffic fall into a "legally questionable" gray area, how can I win in this situation?"
