The reason APRS works is because of the large volunteer army of hams. I wouldn’t say APRS does “mesh”, but with the right path settings it does multihop to get to an igate and on to the internet. APRS has a significant RF and internet infrastructure. I would hope DR could be lighter weight than that.<div class=""><br class=""><div class="">I think that since DR's application layer is using TCP/IP, the NET and Link layers could be more akin to <a href="https://en.wikipedia.org/wiki/6LoWPAN" class="">6LoWPAN</a> and meshing via <a href="https://en.wikipedia.org/wiki/RPL_(IPv6_Routing_Protocol_for_LLNs)" class="">RPL</a>.

I had been thinking of LoRa mesh gizmos and fiddling with designing a mesh transport layer. Ive come as far as two nodes essentially swapping simple json.
