There has been quite some research on it, there where ideas, there was
even talk of a vendor going to implement it, but it never happened. It
won't work because of cash reasons (read: telco/transit don't want it)
For your 'city data' check:
http://unstats.un.org/unsd/demographic/default.htm
or for pre-processed files:
http://arneill-py.sacramento.ca.us/ipv6mh/ under "Geographical data".
especially:
http://arneill-py.sacramento.ca.us/ipv6mh/geov6.txt
will be quite of your liking.

Allocation: IANA block =3D 2346::/16

Allocation: 6bone block =3D 3FFE:FB00::/24

Which indeed seems quite reasonable. The problem with this is:
'who is paying for which traffic and to whom'
One solution is an overlay network....
Notez bien, though this solves multihoming, it doesn't solve relocation,
thus if your company moves it has to renumber, and renumbering is no fun,
then again, you can most likely start from mostly scratch in the new locati=
on
and you might be able to tunnel (parts of) the old allocation to the new si=
te
depending on which subnets/hosts one has moved already.
Greets,
