yeah, it sorta seems to me like the only logical use case for it is sensors, IoT type stuff but using nostr relays. if the device running the relay also has some kind of wifi mesh capability it starts to become interesting because a wifi mesh can span acres with a few nodes, and if the relays on the nodes are replicating it's a resilient connection, if each node also runs an AP that devices can hop to the nearest good connection. it then starts to become something like a nostr-web. assuming you add protocols for stuff like loading app modules to load into a web app client, the possibilities are endless for turning nostr into the next HTTP
