A. AS numbers are not property.

B. If they were property (and they're not), then at least in NANOG's
region there are adequate laws regarding escheat of unclaimed
property. I interpret this to be what Hank was going for: attempt to
contact anyone with a registered but apparently unused AS number and
"escheat" the ones that go unclaimed back to the registries.

Whether or not this is a worthwhile activity is an entirely different
question for which I intentionally decline to offer an opinion.
