Building the Technology Stack for Internet Freedom (Gigaom)

There seems to be a lot of talk about mesh networking, but I wonder whether keeping off-line caches of websites of interest, combined with a way to update them in a peer-to-peer way using USB sticks or whatever wouldn't be an alternative. I am sure that most (probably all) of the software required exists already, and it has been put into practice effectively before, as many unhappy former Amiga game developers can tell you.
