The statement above raises two interesting questions. First, is P2P really a CDN? When I think of CDN, the first thing that comes to mind is Akamai, EdgeCast, Fastly, Limelight, Highwinds, caching software on dedicated servers, streaming, and global infrastructure. When I think of P2P, I think of PirateBay, Napster, World of Warcraft, and a virus. Thus, P2P enables file sharing between end user computers. It uses none of the infrastructure, software, or tools of a CDN.
