What you describe above is almost exactly the GAPI draft used by MHAP.
The flat level involves 64k areas (an area is a /32), which of them
contains 64k sites.

The draft:
http://www.ietf.org/internet-drafts/draft-py-multi6-gapi-00.txt
Does not have an allocation example, but we have one here:
http://arneill-py.sacramento.ca.us/ipv6mh/geov6.txt
(there will be some cosmetic changes to make the addressing plan
compliant with the 25% clause in 5.2 in the draft, but good enough for a
first look).
