Is the only way to go in my opinion. The French set one up and it was very successful from everything I've read. This PnP Mesh networking idea, which is totally public owned, couldn't not be shut down by anything short of massive sabotage. When individuals own the infrastructure and share it with the world, this kind of thing would become very difficult!
In this model everyone simply uses their own routers as wifi (or otherwise) hot-spots connected to everyone else's node, and all share the network. Volunteers or work groups buy repeaters if necessary for dead zones. If memory serves me correctly, they use some kind of protocol to keep each others activities private, where need be.
It is kind of scary realizing the the public telephone system of dedicated connection, is not necessarily fool proof now, as the same switches that govern the internet are used in POTS operations everywhere now. Public telephone will be totally VOIP before long anyway. I imagine their may be court precedence to arguments against such a law, ingrained in that history if one were to dig for it.
