Yeah Sam, we met the Project Lantern people down in Mountain View during the Mozilla WINS finals presentations. We did talk about the importance of interoperability between all these emerging LoRa-related projects. For disaster.radio, we have been designing a full network stack and routing protocol specifically intended for LoRa networks. You checkout the documentation on it here,
https://github.com/sudomesh/disaster-radio/wiki/Protocol. We are trying to make it general and portable such that other projects can easily implement it on their device. Once we successfully implement it on our hardware, I'd be excited to help other projects do the same.
