Tor: An Anonymous, And Controversial, Way to Web-Surf:
For more than four years, William Weber has helped run a free service called Tor that makes Web surfing anonymous for anyone. Then on Nov. 28, the police showed up at the 20-year-old’s home in Graz, Austria, and accused him of distributing child pornography.
Some good recommendations: (a) run Tor on an organization’s kit (user group, whatever), and (b) host it somewhere other than your home, just in case they come and confiscate the server.
