I don't have any problems with BT shaping... if you want to have a look at 
my script, it's this one: http://www.metamorpher.de/fairnat/
It uses IPP2P, but should work about the same way with layer7.

The main difference between my iptables rules and yours seems to be that 
you are not using CONNMARK to mark BT connections permamently - IIRC you 
can't do without because the filters only match one of the first few 
packets of a connection.

Have you checked your class statistics with tc, somehow I doubt that all BT 
packets go into your P2P class in your current setup.

Well, I'm not familiar with tcng syntax at all. I think this kind of setup 
is weird; in the tcng part no class ids seem to be specified, yet you have 
to use them in iptables to classify your packets. How can you be sure that 
you got the right class...
