Okay, pretty clear answers.  Do I have it right that ARIN
would reserve, say, a /32 for NY, with a dotted line around
a map, then any ISP who applied for address space would get
an allocation from that /32?  ISPs would have to apply for
separate blocks in each gerrymander; local ISPs and IXen
would have portable blocks from their local /32?

Justify = 6-month projected host count?  10 year?
