P2P applications have concerns about the privacy of their users, but do want to cooperate with the ISP to optimize network traffic in a manner beneficial to ISPs.
This is also an area where I think the concerns are overblown. DIRECT bulk-data P2P can't be privacy preserving, because peers know the peers they get data from. You can try to be privacy preserving on ENTRY to a swarm (closed world), but once a peer is in a swarm, privacy-preserving is pretty much irrelevant.
Indirect P2P (eg, the UW? proposal recently) is whats necessary for privacy preserving, but that grossly magnifies bandwidth cost, requiring 2 intermediate hops (tor style).
