I just have a perl script run every minute that checks the netfilter
connection tracking for things that behave like p2p traffic and then
firewalls that connection for an hour.  It has been rather effective
so far.  I had to add an exception for very low bandwidth p2p traffic in
order to allow skype.  Fortunately none of the actualy p2p file sharers
are willing to try and share files that slowly so it works OK.

Occationally something gets through in which case we just track down
who is flooding the internet link and go apply a clue bat. :)  One person
got annoying enough that they are now restricted to ftp, http and https
traffic only.  All other traffic is blocked for that user.  They haven't
complained yet.

Expensive packet inspection tools would probably work better, but I
don't have one and really don't want to have to have one.
