	David you know as well as I do that DNSSEC is a orthognal
	issue here.

	The first issue is how do you assign a name to a object?
	The second issue is how do you add that name to the DNS?
	The third issue is how do you sign that change?

	I solve it by give the machine a name.  Adding a KEY record
	at that name to the DNS, the private part the machine knows.
	I then use SIG(0) to update the address records of the
	machine whenever the addresses change.  The DNS server that
	accepts that update generated new RRSIGs for the records
	affected by that change and the zone propogates out to the
	servers using NOTIFY.

	I update the reverse PTR records using tcp-self as the
	authentication mechanism.  tcp-self is weak but is strong
	enough for the level of trust assigned to PTR records.
	Again the DNS server generates appropriate signatures.

	The machine's name is not tied to the network on which it
	lives.
