Combining this with nomadnet would be amazing. If we finally start to see each other... Probably some kind of ecash for routing would be a good idea, lora space is a bit more scarce, but the idea would be relaying messages through rns / nomadnet and the nomadnet node could run a local relay with cache. This would create a decentralized long range nostr.
Most nodes are esp32 too, although we run nomadnet on normal cpu because of the cryptography.
