I'm a core-contributor to Namecoin and the lead developer for Speech.is, an interoperability layer for Namecoin that I have been working on for the past year. While the main goal of the Speech.is website is to provide a scalable interop system that doesn't involve proxies or mirroring content, I was able to backport some of the censorship resistant properties of the Namecoin .bit TLD to regular websites.
Speech.is reimplements DNS lookups within the browser itself. When coupled with emerging WebRTC P2P networks we are able to push all processing to the client side, shielding us from legal liability. The special speech.is#name.bit syntax makes it impossible for governments to selectively censor websites and very difficult for politicians and judges to rationalize their way into blacklisting the entire domain.
The www.speech.is website has the full nitty-gritty, but remember that this is a developer preview!
