I like the TOR browser, but from the content side, I also like the idea of using the current Internet to eat itself.
A site like Wikileaks or EFF could make itself REALLY useful by having multiple domains spread out all over the place, and offer subdomains to whomever wants to sign up in Turkey, Iran, China, whereEVER they want to sign up from. And the URLS are unassailable from the inside of that particular country.
People can say what they want on their site since it's offland; there are no local laws that can touch it. People need to use strong encryption and hide their tracks to update their sites, but that's not too hard and could be built in - no open transactions allowed, TOR required for site work.
That's not to stop a country from blocking those URLs. But at least the people who want to speak out can say whatever they want to, cover their tracks, preserve their freedom, and get the news out.
