TorrentFlux
TorrentFlux is a free and open source multi-user GUI for BitTornado. Unlike most BitTorrent clients, its main user interface is a web interface. It is scripted in PHP, with a MySQL database and runs on a web server.
Its web interface allows it to be operated on a remote server, which is useful for file services based at an Internet service center.
The most recent beta release also includes support for ADOdb, allowing for use of other database backends. Numerous "hacks" have been written to add additional functionality.
