Mark Cuban to ISPs: block all P2P traffic

In an open letter to Internet service providers published earlier this week, billionaire entrepreneur Mark Cuban calls for telecoms to put an end to peer-to-peer (P2P) file-sharing. Cuban expresses concerns that P2P "freeloaders" are clogging the tubes with commercial content. His letter doesn't focus on piracy, however, and instead primarily attacks companies that use P2P for legitimate commercial applications.
"If I was a Comcast customer, I would tell them, as I am now telling all the services I am a customer of: BLOCK P2P TRAFFIC, PLEASE. As a consumer, I want my Internet experience to be as fast as possible. The last thing I want slowing my Internet service down are P2P freeloaders," says Cuban.
"I wanted to offer the best alternative to P2P for audio and video..... Google Video. If you are trying to do distribution of audio or video, why in the world would you use P2P when Google Video will host and distribute it very efficiently and for free?"
