This looks promising!

From their website:

"What is psiphon?

psiphon is a censorship circumvention solution that allows users to access blocked sites in countries where the Internet is censored. psiphon turns a regular home computer into a personal, encrypted server capable of retrieving and displaying web pages anywhere

Who will use psiphon?

psiphon operates through networks of trust. There are psiphon providers who install and administer a psiphon server (psiphonode) in an uncensored country, and psiphon users (psiphonites) who login and access the server from a country that censors the Internet."

Is psiphon anonymous?

psiphon is not an anonymous software program. psiphon users are not anonymous from the psiphon provider. Although traffic between the psiphon user and psiphon provider is encrypted, psiphon providers can potentially monitor everything that is done by the psiphon users they host."

I seem to remember that there is a tool like this out there that was developed by the U.S. Navy; but I don't remember it being very easy.

Now it also seems that if someone in the government of a country that censors like China wants to catch folks browsing prohibited sites, they could run one of these servers/nodes and monitor easily what these folks are browsing.
