Re: Still sounds like....
None of the p2p applications use IETF-registered protocol numbers; they're all completely variable, which is why it's generally impossible to filter (similar to IRC servers in respect of implementation).
I've never seen any of those products until now -- thanks for pointing out that stuff like this does exist. I'm always proud to be wrong, especially when learning new things.

They would not need a layer 7 device.
p2p operates in generally the same ports. It is not difficult to block or slow those particular ports.
There are plenty of devices out there, in case you did not want to use a router, that can be put "into a line" to control traffic. You would be surprised how many ISPs do use these devices. PacketShaper is one that comes to mind or maybe even etinc. Here are a few of the links...

Juniper and Cisco are not the only products available. PacketShaper is a carier class design and can take gigabit links I believe. I have seen these at ISPs.
