Because this KISS-TNC stuff is pretty old, it has really good support on modern Linux.
So we're actually able to setup lorapipe on two different linux boxes and form an ethernet network over LoRa!
The current rev has some MTU limits we can fix, we can also eak out probably another 2x more bandwidth too.
But as is I was able to ping, mosh and ssh over my ethernet-LoRa network between Linux computers!
