We actively enforce our policies forbidding the use of university
resources to breach the copy rights of third parties.  We do this mainly
by monitoring traffic with snort to detect the various p2p protocols
using the bleeding snort signatures and the Sourcefire produced signatures.

When someone is detected running a p2p app we send them a formal notice
stating the university's policy and requesting that the user cease and
desist if the material they are accessing is being copied illegally or
give us the details of what they are doing if the copying is legal.

This seems to work well.  I usually issue no more than one notice a week
(usually to a visitor or someone who forgot to turn off limewire before
connecting their laptop to the network).  There are several staff on
campus who use BT to download software but we know who they are now and
ignore alerts generated by their traffic.

In our residences we have banned p2p file sharing apss all together.
This is enforced by packetfence which again uses snort to detect
violators who are immediately barred from the network.  Packet fence
also will detect infected machines and get them off the network too.
