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.

Which is basically a bad idea, as I have explained in my
previous mail.

May I ask why do you need to do that? Are you operating
an internet router for untrusted users?
