Neat, thanks. I have another follow up question based on when I tried to use off the shelf clients (damus, iris, snort) with a single private relay and kept seeing events leak into public relays… are you worrying about the problem of using existing clients and preventing them from re broadcasting notes to relays which might be hardcoded (or cached maybe) in the client code? 

Back when I tried using a single private relay between multiple off the shelf clients, my process was:

1. Download a client
2. Remove all initial relays in settings
3. Add my private relay
4. Use the app

And I couldn’t get events to stay off the public relays.

Granted this was a while ago, and if a client can render an event, then it necessarily has everything it needs to send it elsewhere and a code audit might be the only actual solution.

Anyway curious if you’ve thought on this and are focusing or testing this problem at all?
