At some point, somebody will set up long range wireless communications and then the reward for running a message would likely drop to so small that it wasn't worth it... but yeah that's exactly the sort of thing that I had in mind. That way if something happens to the internet, prices for running a message go up, and suddenly running messages is worth it again.

The tricky part there would be working out a partition tolerant payments system. It's one thing to go offline in the middle of delivering a message, its another thing entirely to orchestrate payment across a smattering of disconnected networks (blockchains are not partition tolerant). I think it could be done, but that's an application layer concern... gotta get the peer finding and web-of-trust stuff working first.
