fixed geographic allocations (another nonstarter for reasons which have been elucidated previously)
What I hear is "any type of geography can't work because network topology != geography". That's like saying cars can't work because they can't drive over water which covers 70% of the earth's surface.

Early proposals for doing any geographic stuff were fatally flawed but there is enough correlation between geography and topology to allow for useful savings. Even if it's only at the continent level that would allow for about an 80% reduction of routing tables in the future when other continents reach the same level of multihoming as North America and Europe.
