Have you read my draft? The only thing that it _requires_ is that the  
RIRs start giving out address space with geography in mind. I don't  
think this requires upgrading much humanity or even business  
processes. Actually implementing the aggregation then has some  
business impact (going from hot potato to cold potato) but since every  
AS can decide for itself if and when to do this, that's simply a  
tradeoff: what's cheaper: transporting traffic over some distance, or  
buying bigger routers?

BTW, has anyone considered the issue where large international  
organizations with many offices may want to advertise a prefix for  
each office rather than a single one for the entire organization?
