Daniel, there had been material on this, but in the Content delivery and distributed file sharing networks article. I've moved the details to the main page here, and will take the image out of the definition.
Are there specific things you'd like to see expanded? I'm not a BitTorrent expert but have worked with it a little. Otherwise, I'll expand the CDS article. --Howard C. Berkowitz 15:35, 17 April 2010 (UTC)
