It would be nice if you can add some (basic) torrent funcionality in FRD!

That way, FRD could become Ultimate Downloader ;)

Is it even possible?

Maybe yes.. if there is some free java based torrent library we can incorporate here.
I don't use much torrents.. also there are few torrent to http services.
But yeah it will be nice if we get torrent support.. especially after that utorrent bitcoin miner thingy.

No, unfortunately this is way out of scope. Bittorrent is a complicated system which is best served using a dedicated program.
