I want to run a small Go or Rust (khatru, haven, rs-nostr-relay, or chorus) based relay on a Raspberry PI, obviously its going to be using web sockets but I want to also connect to it over a USB serial interface like the https://github.com/lnbits/nostr-signing-device

My goal is to build a personal pocket relay that can connected to wifi (and discoverable) or connected via USB to a computer and managed from there.

Bonus points if we could also find a way to talk to it over Bluetooth, although I doubt ble has enough bandwidth
