Hossein Derakhshan has a recent blog post on how peer to peer news readers can help fight censorship:

Imagine a peer-to-peer news reader that not only syndicates RSS files, but also downloads them and share them with other users. So you'll never be blocked to access any piece of information as long as you have access to this peer-to-peer software. It could even be implemented in the browser or added as a plug-in for an existing newsreader.
