	DNSSEC allows you to go from dns name -> CERT in a secure
	manner.   The application then checks that the cert used to
	establish the ssl session is one from the CERT RRset.

	Basically when you pay your $70 or whatever for the CERT
	record you are asking the CA to assert that you have the
	right to use the domain name.  It's expensive because they
	are not part of existing DNS trust relationship setup when
	the domain was delegated in the first place.

	The natural place to look for DNS trust is in the DNS.
