That what I was thinking too.

I'm working on HAMSTR, and will soon have kind 1 notes totally complete, working on DMs, search, and some other stuff.  Can't do off-grid LN payments or zaps easily, but was thinking perhaps an easy way to send Bitcoin from an off-grid client over ham radio.  maybe I'll build it into my server to broadcast a tx if a certain note message is received, not sure.
