You might find it interesting/useful to read about: steganography[1], anonymous remailers[2] (particularly the Mixminion[3] type), the Paranoid Security Guide[4] (which was on HN today[5]), and a nice talk on privacy and anonymity options[6][7] There were also a couple of lists of darknets on HN recently, but I can't find them right now.
