And that's one of the things two domains with different registrars protects you from.
There are almost zero protections from registrars; You may remember when panic.com had their domain stolen from them from a registrar that wasn't even theirs. You can't have a single domain with more than one registrar, so there is no way to protect from it.
Likewise, it is not clear whether having each of your nameservers be on a separate domain at separate registrars would protect you from Die Daddy. If they modify the ROOT server records for both/all of your nameservers regardless of where their domain is registered, you're still dead. Which is what Die Daddy should be as well.
Yes, I remember the Panix mess. If godaddy went in and modified the root record for a customer not its own the inappropriateness should be completely obvious, as would be the corrective action and appropriateness of great urgency on godaddy's part in taking that action.
In that case, it might be a crime, since I assume it does not have authorised access to the records of those not its customers, who have no agreement with it.
