My assumption has been that BitTorrent is used mainly for dowloading software (and movies, I guess) illegally. Why take the risk? Buy the software.
I recently used BT to download all six games in a Humble Bundle collection sale, available either via slow download link on their site, or download their torrent links and get them that way. Several gig of data. MUCH faster that way.
Companies are starting to realize the value of bittorrent, or at least P2P content distribution. (and hah... autocorrect wants to make that "bitterness")
