Every wireless router & device should have been shipped, from early on in the history of WiFi, with default-on support for ad-hoc networks. Few and fragile at first, in many areas would have grown to a robust "backbone" by now and will only grow larger & stronger with device proliferation. Account for priority traffic & battery life, of course, but even low-level support would have grown very difficult to intercept. Alas, the desire for central control, as usual, overruled.
