Just to clarify the terms I was using:
- Operator: the servers that get shards of the keys -- your key could be split in 5 shards and each of these shards be with with one of these, then you need 3 of them to participate in order to perform a signature or recover the key, for example.
- Central: the server that coordinates with the operators and offers a NIP-46 bunker interface for Nostr clients to connect to.
There is a gimmick that works today: when you create your Pomegranate stuff with one of the Centrals you publish an event with a hash of your email address and that Central's URL. This way even if you connect to the wrong Central when logging in to a different client that client can still learn your email address and query some public relays what is your actual Central URL, and log you in to that one instead (you'll have to click to authorize again probably).
This scheme wasn't super well-thought, so maybe it has some flaws, but it works. So a world with multiple Centrals is already possible.
