Yup, see:

Just my thoughts from a random user

• Have communities work similar to how RAID works with drives. It spans across multiple trusted instances, with data mirrored or striped to each. If one goes down, a new instance could become trusted and have the data rebuild on that instance. This would create redundancy and prevent one instance from becoming the main or default.

• Allow similar with user accounts or allow instance migration.

I use Element (Matrix) to talk to friends and family. I really enjoy the Fediverse, it feels like we’re going back to the user owned internet.

Honestly thought it sounded cool, like a realistic kernel service.

Who can figure it out?
