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.
