Interesting, but would you know about a FOSS solution for Windows? That would be really great.
Setting up a GNU/Linux gateway for only one computer that is powered off when I'm not using it seems like an overkill.
If I had a set-up like that I could leave torrents to work at night and and had no need for traffic shaping.
I wonder after what time such gateway would consume energy worth those 15 euros I've spent on cFos...
As for the irony - it only works if we label torrent traffic as illegal-only and assume those that download things "for free" will pay for their copy of cFos.
