even better will be when these run lightning... if you just add this QoS field to LN nodes it would be possible to make them more tolerant of being out of reach and also to be able to directly contact via LoRa or Meshtastic or whatever

ecash still requires connections to mint nodes and there is a potential for in mesh networks with LN for you to have a private channel with all your regular business associates so you literally even can just hook up to their wifi and zap them

it just requires the LN node to have an understanding of intermittent and long-time-disconnected states being ok
