Sounds like you need a client on the NAS with the WebUI that you just paste magnet links to, no need to have any torrent software on your PC.
That does sound ideal. Looks like Transmission could work on it. Not sure how easy to get it working. I'll look into it I think.
Have you ever managed to get the client/server method working with Deluge?
I have the daemon running on my Pi, and wanted to run the client on our laptops. Basically make it function as if it were u torrent running locally, but all the downloading happening on the Pi.
I got it working fine with the Web interface, but I find it a bit clunky compared to running a native app (and also lacks the file association integration stuff)
I haven't even looked at that but I might. I just purely use the web interface to admin the server, seems to work well enough for me.
If I could make Chrome open the webinterface and pass the magnet link when I click on a download then it'd be all right.
I use qbittorrent, which is pretty much μTorrent without the annoyances, but with some of the nice visual touches missing as well.
Looks like that works the same way as the deluge client, but I'll give it a whirl.
Is that stable now? Last time I tried it was really flaky :(
