If you want to use some other node as a “backup owner” in case first node dies, you can set fallback property, and that second node will become a new owner when the first will be gone for some time (not yet implemented). In future version every domain will need to be “bought” by PoW. Simple mining of nonce, that will eliminate squatting, or make it hard enough.
