The University of Illinois at Urbana-Champaign is doing something very similar.

http://www.housing.uiuc.edu/technology/urhnetsecurity/rate_limit.htm

"Unrestricted Class (10Mb/s): By default, connections are in this class. The connection is not artificially throttled or limited. Restricted Class A (128kb/s per flow): When the Internet traffic of an IP address reaches 80% of the limit (600MB), the IP address (computer) will be rate-limited (throttled) to 128kb/s per flow. Restricted Class B (32kb/s per flow): When the Internet traffic of an IP address reaches 100% of the limit (750MB), the IP address (computer) will be rate-limited (throttled) to 32kb/s per flow. Restricted Class C (512kb/s aggregate): When the Internet traffic of an IP address reaches 150% of the limit (1125MB), the IP address (computer) will be rate-limited (throttled) to approximately the speed of a 33.6 modem (about .32% of the bandwidth in the unrestricted class)."

"Q: Will I ever get shut down for traffic? A: The current "rate-limiting" system does not turn off ports it just slows down your connection. However, rooms and computers may still be turned off for many other reasons (viruses, copyright, abuse of the network, and for very large amounts of traffic as determined by the CIO's office)."
