i did some work with broadcasting nostr events over lora mesh networks. it works as an experiment but isn't practical.

the size of the data packets needed for Nostr events is too large for nice behaviour on LoRa. I've not tried with other frequencies but I expect similar issues.

There are workarounds I've thought about like using a nip46 signer to reduce data size, or having a single gateway that constructs and signs all messages.

There's something in it but needs more investigation.
