Will require a lot of integration work with SV2 and RNS
You could run something like Reticulum + LXMF over airMAX to WAN links

Think like a SV2 proxy that does a couple of airMAX hops to some point that has internet access.
Reticulum packets are under 300 bytes, by far the least amount of bandwidth of any protocol I've seen.

Discussion
You can pipe RNS over TCP & UDP
Saw they were working on a reticulum ATAK plugin
Also I saw another person with a Neros handle in the matrix group chat. I think the MIC has found #Reticulum
I know! 😅
Just need a byte stream that can turn into r/w halves.
