Its not a bad ideia since I see a lot of people searching for P2P traffic control/shaper. I'm operating an ISP with 3000 broadband users ... And yes. I can call they untrusted, but this is not the point. With ipfw I can do per IP traffic shaping, but what about if I can limit a IP in 256kbps and say that this IP will be able to use only 128Kbps for P2P traffic. As I said, I do this nowadays creating rules based on P2P ports, as well as m0n0wall do. However it is not efficient as iptables is. I tried a linux based system ( Mikrotik ) to limit P2P and it matched almost 100% of P2P traffic ... And as I know, ipfw can't do this. And maybe this kind of string match can become useful to other things.
