nice link.
Tor is very reputable, because it is supported by the Electronic Frontier Foundation

The blog mentions privacy protection at 80% (no idea how that number was chosen), but I'm surprised at the claim of usual torrent speeds. I'd heard the bt users were really slowing TOR's effectiveness.
I keep meaning to try TOR and Pivoxy . . . . thanks for the link.
