Hey, folks!
Several people have suggested that I replace the anonymous proxy I used to run with a Project Tor router, and I have done so. What a neat idea this is! If you have a DSL line and can spare at least 20 kilobytes (160 kilobits) of bandwidth both in and outbound, and want to strike a blow for privacy, I strongly urge you to check out this software;
http://tor.eff.org If you don't have that much bandwidth, or don't want to share it with others, tor installs by default as a client only system and give you totally anonymous access to the internet.
It works by transmitting your data not to its final destination, but to a randomly chosen participating Tor router, such as the one I now run. That router either hands it off to yet another router, or sends it on its way to its destination. Each and every time you start an application to surf or run irc or whatnot, you will appear to be from a different part of the planet.
This is of great use for Whistleblowers, as you can do things like send a hotmail message without your IP address ever appearing in the header of the email, and there is no means whatsoever of tracing you back to the source. The tor system keeps no logs of any traffic!
This is also useful if you want to mole onto RW boards without them knowing who you are!
If you try it, let me know your experiences with it. I just finished installing it here, and so far it works great.
