Utility Room

Tried BitTorrent, Tomato Torrent and Transmission. I chose Transmission because it was lighter than BitTorrent and supported drag-n-drops of web page links which Tomato didn't do.

Azureus was out of the picture because I didn't feel like installing a resource hog Java app. Didn't try BitRocket.

I got the BT client because I've been bumping into a few open source apps that offer bittorrent downloading (which I'd rather use because that way I'm not using as much bandwidth from the nice folks who offer their product for free).
