Not true.
Geographical addressing means that a provider uses addresses
from a city aggregate for all infrastructure and customers
in that city. The city aggregate would be determined and
administered by RIPE. All providers who have infrastructure
in Paris, for instance, would ask RIPE for the number of
Paris addresses that they need, regardless of the size of
the operator or their dominance in the market.

There already are "leading" operators and "sub-level" operators
in the Internet access market. Geo addressing does not change
this because geo-addressing is a technical solution to a
technical problem of packet routing.

The vendor doesn't need to implement IPv6-BGP-4+x on
the router if servers in the operator's management
systems are doing the IPv6-BGP 4+x function and passing
the instructions to the routers using plain BGP4.

And the whole point of geo addressing is to avoid the update
of underdimensioned forwarding engines when insurance companies
require every company to be multihomed in order to qualify
for business insurance.

Why is it necessary for routers to speak BGP in order to 
maintain a view of the relatively stable mesh of AS interconnections?
Why don't more people do this work with servers which are
faster and cheaper and easier to swap(upgrade) than routers?
