This is an interesting and very important point. There are quite a few legal
things being distributed via BitTorrent these days, for example.

I think the best you're going to manage without massive time/money
investments in deep packet analysis is, as others have suggested, increase
priority on known "allowed" traffic, and reduce P2P bandwidth to a very low
(but still usable if nothing else is using the bandwidth) level.
