LoRa mesh routing is so going down the route of Internet routing in the 1980's, it's spooky!

How does this differ from Reticulum?
Reticulum works bottom up and is focused on the protocol enabling you to emulate any network, even TCP-IP.
Meshtastic works top down, and focuses on the functionality. It primarily uses devices to relay messages.
WiFi-based meshes are underexplored.
We've been trying since the early 2010's to do this in public networks.
Look at TTN, SIGFOX and later Helium coverage maps.
I'm not sure this fixes it, but previous LoRa networks were too commercially focused. This has "fun" built into it. Enthusiasts war driving around texting node operators brings these networks to life, so perhaps the hobbyists can do what the professionals failed to.
