Oh no. I mean, it COULD be done, but Vuze is a heavy resource using Java program. If someone made a special N900 version though it would be cool.

If you want to control BitTorrent and download stuff with your N900, but not TO your N900, you wouldn't have to have ANY torrent client on your N900. For instance, you set up your home server box or main PC with Vuze/Transmission/Deluge etc.. any client with a WebUI. The WebUI spawns a webpage administration server that will control the torrent client. Then you use your N900's browser to connect to the admin webpage and say, point it at Torrent files to download and where to put their contents. You could do it all from your N900's browser!

Now, if you wanted to download TO the N900 itself, that's something different.
