When traveling through Lake Tahoe, someone had a node with mqtt setup. Had dozens of nodes connected through to the EU and a couple in Russia. Potentially an awesome out of band coordination layer. I need to play with these features
I have been warned that MQTTT can be very spammy, so use this feature with caution as the network protocol is susceptible to spam. If we apply similar engineering logic to #mesh as we do to #nostr and #lightning, we may be able to mitigate some spam issues, like we do for nostr #relays.
