If you're BitTorrent and you want people using their client in the browser, this project makes a lot of sense. >plugin only works on Windows I haven't played with it yet, but it ran an installer on my Mac. You might have been confused since it detects your operating system and just installs the right version, not letting you see which systems are supported. >have to manually install a third-party plug-in It is mostly automatic, but does ask you since plug-ins run native code and present a significant security risk. I am guessing it might be necessary to use a plug-in because it requires more access to the system than Flash provides (at least in the security model that it gets run in within the browser) and also perhaps because it allows reusing existing code.
