Geographic routing strategies have been all but proven to irredeemably violate the recursive commercial payment relationships which create the Internet's topology. In other words, they always end up stealing bandwidth on links for which neither the source of the packet nor it's destination have paid for a right to use. This is documented in a 2008 Routing Research Group thread. http://www.ops.ietf.org/lists/rrg/2008/msg01781.html If you have a new geographic routing strategy you'd like to table for consideration, start by proving it doesn't share the problem.
I think the problem can be tackled by implementing this in wireless last-mile networks owned and operated by end users. (Obviously the /64 space is enough to carry that information. Long-range could be done via VPN overlay over the Internet). This will reduce the local chatter for route discovery and remove some of the last-mile load on wired connections, which is in ISPs' interest. I think we'll see some 1-10 GBit/s effective bandwidth in sufficiently small wireless cells. If this scenario plays out, this will inch up to low-end gear like Mikrotik and eventually move to the core. I don't think this will initially happen in the network core for the reasons you mentioned.
