Geoff's numbers are based allocation rate.

We actually have been fairly creative (e.g. moving IPv6 and ASN 
requests to additional resources to free up more time for IPv4
requests); there are other similar options if needed, so I'm 
going to disagree on that assertion of a "max carrying rate."

The amount of time to process such requests is highly dependent
on the preparation level of the requester and the policy which
is defined by this community; both of these are to-be-determined.

It could be much longer, depending on the requests for smaller 
blocks versus more mid-sized (which will end up on the waiting

Complete runout is unlikely to be cleanly predictable; e.g. in
the APNIC region, they still have IPv4 resources but are issued 
per their austerity policies.  In the ARIN region, we'll be "out"
when the first request is approved but there not IPv4 resources
to fulfill the request and the waiting list policy is triggered.

See above... Geoff has been predicting effective depletion based
on run rate, not complete lack of IPv4 resources in the region.
