Huh, I wonder why Tom Nardi thinks there is a plan to run Signal over LoRa mesh network. 🤔

Normally hackaday authors would back up claims like that with a link to their source, so I suspect it's just conjecture, not a plan of someone who contributes code to either Mashtastic or Signal.

I agree it'd be another way to address the issue, but it would also require a gateway to the internet. It would not solve anything for off-grid communications.
