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.
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).
If an endpoint is allowed to have multiple addresses and allowed to rapidly change addresses then a more optimal last-mile solution is dynamic topological address delegation. Each IP represents a current-best-path coreward through the ISP's network. When the path changes, so do the downstream addresses. Instead of a routing protocol you have an addressing protocol. In theory, such a thing automatically aggregates into very small routing tables.
