I see, so a coordination server is necessary which kinda somewhat defeats the "mesh" claim, though I do wonder if achieving this in a manner similar to DHT could eliminate the centralized entity controlling the servers at least, allowing the "peer-to-peer mesh" claim to be there in spirit.

Not that I have anything against the software or company to be clear, just that I wish one of these p2p vpns would be _totally_ actually independent of any coordination server or central entity!
