Hi Florian,
Thanks for this wonderfull workflow ! Works great with a local transmission server (same machine).
Free (french ISP) use a transmission server on his last box named "Freebox".
To manage my torrents directly on the Freebox, I'm using "Transmission Remote GUI" ( http://code.google.com/p/transmisson-remote-gui/ )
I'm a very rookie (un bleu bite complet in french) in scripting / coding / ... But is it possible to adapt your workflow to the transmission server on the Freebox ?
Thanks / merci
