A Crunchbag.com article on "Remote Torrent Downloads Via SSH" just hit me right on the spot. I have been looking for a way to do this for the exact same reason as stated in the article, "...maximise the potential of my 512k ADSL line by using it for downloading torrents when I'm connected to a different network.", although in my case, I have a 2Mbps connection.

Currently, I am using Azureus with the web interface plug-in but that requires the remote desktop to be running a GUI, which takes a toll when accessing it remotely. See? Who says command-line interface is dead? Hahaha. Anyway, I will give this new tip a try and see what happens.
