I have been doing this for a long time, in fact I wrote about it on XBIZ over 2 years ago.

Lot of things has changed in the past 2 years but concepts are same. The hardest part in P2P is getting file density so when a user search for "milf" your movie shows up on top. It?s like SEO, lot of tricks, custom software, a lot of servers (one of my clients got over 1000 servers) and a lot of Class C IP space.
All my P2P work these days are done for main stream clients because the money is more on the other side of the fence. I may write another article about my experience on P2P marketing for AVN or XBiz on this subject if there is much interest
