I think a distributed .alt where people can have a "backup" of their domain would be nice. gun.io with gun.io.alt running concurrently on the distributed system. It would be a nice reference to the alt.* Usenet split in response to attempts to control it. The underlying technology and how to arrange it is another question though. Edit: Mcantelon's reference elsewhere in the thread to namecoin looks like a good start http://dot-bit.org/Main_Page
