	these questions were asked in response to Owens views on
	the ARIN reclaimation process in the case of documented
	transfers outside the existing ARIN processes.

	my assertion to Owen was that his views would apply directly
	to the folks under a standard RSA.  My reading of the
	LRSA suggests that ARIN has a much narrower remit on recovery
	of resources covered by that document. the third camp was/is
	a much thornier patch of ground, fraught w/ peril if ARIN
	takes action on recovery, at least imho.  #4, well that sounds
	like fruitful ground for inter-RIR coordination.

	for example, if 75% of the total resource under ARIN administration
	is legacy, then 25% is covered by the standard RSA.  Within the 75%,
	6% of it is under LRSA and 15% of it is under the standard RSA.

	if this characterization is in ballpark, then Owens view on
	reclaimation only holds for ~30% of the resource under ARIN administration.
