Controlling things happening at home remotely from your smartphone has become a big area of interest for the tech savvy consumer. The newest toy for those is the uTorrent Web project, currently known as "Falcon."
This program has improved upon their already interesting process of controlling your uTorrent uploads and downloads on the go by customizing their interface to play very nicely with the iPhone. Android phone users shouldn't fret; the program seems to work just fine with your phones as well. Touch interface for adding, starting, and stopping torrents is reported to be smooth and easy to use.
