I don't believe BT will truly take off until web seeding is functional in all clients and I can use (a site | series of sites) to make a torrent of an existing thing. There was such a site (whose cute URL escapes me) where one could plug in a URL, it would download and cook a .torrent file but with the web seeds pointed at the source, and from that point forward others could get the cached version and the process was bootstrapped I was also saddened by AWS dropping torrent support from their S3 API because that's one more easy way that folks could provide torrent bootstrapping "for free"
