Yes.

Agreed. The size of v6 allocations is not related
to the number of hosts. Hostcounts are v4 thinking.

Yes. And since this requires an ASN and since there are
some 12,000 ASNs in the ARIN region this would tend to
limit the number of end-user PI blocks to the 5,000-10,000
range which some people desire.

Yes. Why do people need IPv6 addresses? To deploy a network.
How do they prove that they will deploy a network? Show
that they have already done so using v4 addresses.

More or less. Round this number up to some rational
bit boundary. And I assume that the "already deployed"
refers to preexisting v4 deployment.

No, too restrictive. I agree that we need a verifiable
definition of "site" but I think this can be done in a 
way that allows multiple sites per city. Two possible ways
to prove it to ARIN analysts are to provide an IP address
per site that can be tracerouted to show a unique path
or ISP bills/contracts that demonstrate one circuit per
site. I'm sure that there are other ways of proving site
count such as municipal tax bills, water bills, etc.

Rather than define "site" we should refer to IPv6 RFCs 
which talk about how to assign /48s. As long as the count
is consistent with IPv6 network design practices, it should
be allowable. If a company has one router per floor of
their building, then it is one site per floor. If they
have one router per building on their campus then it is
one site per building.
