This mirrors an idea that I had. TOR is a military project, and you know at least some of the exit nodes are controlled by the US gov't. Why not replicate TOR with a botnet? Bounce your communications around a plethora of average joes and you have yourself a more stable tor. If you spread the botnet without a CnC server and have the infected machines bounce random traffic around, it would be damned difficult to break. TOR is open source, so it shouldn't be too hard to modify it to work on a private network. The nice thing about it is that if you attract to much heat you can always ditch the network and start a new one.
