The Deluge Team - 24.48MB (Open Source)
Deluge is a feature rich BitTorrent client for OS X, Linux, Unix and Windows operating systems. The application uses libtorrent in its backend and features multiple user-interfaces including: GTK+, web and console. Deluge has been designed using the client server model with a daemon process, which handles all the bittorrent activity.
The Deluge daemon is capable of running on headless machines with the user-interfaces being able to connect remotely from any platform at all.
