ok, so DNSSEC makes it hard to spoof DANE records if the root domain's 
DNSSEC public key is baked into the client.

it however makes the root domain (.) DNSSEC private key the single most 
valuable secret in the history of the world.

What happens if this gets out or gets stolen or brute-forced?

At least CA certs expire, and there are lots of them.  This is seen as a 
negative in the DANE RFC, but it can be a positive in the 
all-eggs-in-one-basket argument.

Sorry if this is O-T, but if we're building the internet on DANE....
