Well, most p2p apps live on well-known ports, and Cisco's QOS mechanism
allows easy classification on ports.  Yes, most of the p2p apps are
port-agile -- but only if they are completely blocked.  My experience is
that if you let the p2p stuff through, it'll stick to its default port and
you can police with impunity.

If that's not good enough, Cisco's software routers (i.e. not GSR, Cats) can
find Napster and Gnutella on any port based on packet contents.
