yeah, being able to delegate signing to the relay to enable it to reach out and fetch your events for you pre-emptively would be amazing... one that only allows your friends to connect to it, and has inbound routing via a wireguard tunnel and reverse proxy, it is a complete package, all we need is to add this to the relay so it can proactively fetch events from relays it knows your friends also use, let them directly deposit their events in your relay, especially your DMs...
but don't tell the Opensats grantees about this, they will rant all day long about how auth is doxxing yourself and all this other nonsense lol
