This was already done by Facebook and I assumed removed for liability reasons. See: http://en.wikipedia.org/wiki/Wirehog http://en.wikipedia.org/wiki/Wirehog Though I do agree that the distributed nature provided you have encryption will make it very hard to catch people sharing files. Though if you stream the videos/images/books from your site to read/watch them you can get caught at that point(If ISPs complied with CopyRight enforcement strategies.)
