Avoiding the side-issues of Bannedmusic.org's efforts, they present one of the most concise formulas yet for making BitTorrent downloads more of a no brainer -- a self-installing copy of BitTorrent with the torrent file, wrapped in a Nullsoft Installer (they even provide a wrapping script.) While this only works on Windows machines, it installs BitTorrent (so in the future people can just download the torrent file, which seems a slight improvement over Blizzard's approach.) They also included a link to Azureus, a Java library for building BitTorrent applications.
