	How do you expect anyone but the largest of the large and extra large
organizations to qualify for a /20 of IPv4 space under this proposal?

	This is a really interesting way to attempt to reserve the last /8 for use
only by the largest organizations ARIN serves, but, I really don't think that
is good policy.
