Caching and 'tracker optimisation' has been happening for a while, P2P flows being redirected to on-net peers to save transit bandwidth. Potentially while P4P makes some intrusion easier it's fairly trivial still for ISPs to poke into P2P flows, especially with the sub-standard encryption that's employed in such clients. Worst case ISPs could even proxy the encryption transactions if they had to.
This is quite an interesting technology actually, I might have to do some reading into it and educate myself a bit
