Redundancy: Multiple instance of the same wallet for staking



How does Ouroboros identify a unique node? Is it by wallet address?

I’m thinking of setting up Daedalus in multiple sites to provide redundancy when staking. Same wallet (restored using pass phrase) in different locations. I hope that this will reduce the chances of unavailability due to network issues when chosen as a slot leader. Will there be problems with Ouroboros in such a setup?

I also heard that Cardano will be signing up beta testers for staking and stake pools. Please add me to the list.
