> It's probably reasonable that radio hardware can't trivially be reprogrammed to exceed regulated power limits.

The true limits are imposed by the hardware, not the software, as it should be!

An experimental mesh network protocol, that is still very much beta and missing some features.
The big thing I wanted to try is automatic global routing via MQTT.
Everything is globally routable. You can roam around between gateway nodes, as long as all the gateways are on the same MQTT server.
And there's a JavaScript implementation that connects directly to MQTT. So you can make a sensor, go to the web app, type the sensor's channel key, and see the data, without needing to create any accounts or activate or provision anything.
