Isn't the problem with this, single points of failure? I guess it's still more of a mesh than the current infrastructure. But if you're trying to 'route around the government,' then having a defined structure seems counter to your goals.
A full mesh is impossible. It just doesn't scale. You need a fractal system. You also need graceful degradation (or progressive enhancement). It would be great to push a tweat out, and have it visible on the local network until the local network can sync with the central server.
