Isn't that the definition of off-grid?
The routing is simple. Every node repeats everything it hears. A message goes out with a counter - defaults at 3, maximum 7. Every time it's repeated the counter is decremented. At 0 it won't be repeated any more.
You can DM nodes you've seen. You can create your own encrypted channels with a pre-shared key. You can link meshes over the internet through MQTT if you have an internet connected node on each mesh.
Yeah, but not only. For example, I can build a private wifi network, and have my friends join their phones to it. Some bloke across the yard can open his own network, but the two networks will not communicate with each other. The two networks are off-grid, but are independent of each other.
This meshtastic thing sounds awesome! Crowd sourced off-grid network.
