Released just this Dec 1st, psiphon is a human rights software project developed by the Citizen Lab at the Munk Centre for International Studies that allows citizens in uncensored countries to provide unfettered access to the Net through their home computers to friends and family members who live behind firewalls of states that censor.
If you are in a censored country, you’ll need to access a psiphon node in an unrestricted country. Check out the tutorial for how to get started. Seems like the bottleneck will be getting access to an unrestricted node. Right now, you have to do it through the psiphon forum and personal message. The forum seems to be filled with people in China wanting access to Wikipedia.
