Packeteer has various patents covering tcp rate control and everything else
they do, including the "idea" to look at upper layers to detect the type 
of traffic.
I live in germany so i don't really care that much about their patents 
(they had none
in europe last time i checked). last summer i started implementing tcp 
rate control
as qdisc for linux. i haven't worked on it for a couple of month now, 
but if anyone wishes
to participate i would be glad to dig out my source again. it is 
basically working, the
remaining problems are mostly how to detect and handle interactive traffic.
