	there are areas/places where renumbering fails miserably,
	notably within DNS, SNMP, NTP and anywhere applications
	depend on knowing the whereabouts of remote systems, -by
	address-.  Many applications use the IP address to reduce 
	the delay in a DNS lookup. These applications are sensitive
	to wholesale renumbering, often to to point that they have
	no idea how broadly the hardcoded IP address has spread.

	Other than that, I expect that having processes in place
	to evaluate useage is a good thing.
