I always did enjoy a challenge.

It's really pretty trivial up on the whiteboard.  My model includes BGP
confederations to define regions.  In the absence of enough IP Addresses to
divide your allocations by confederate AS, I am fairly sure the use of 
communities could be used to hack the distribution of more specifics into
conforming the way you want.

This is all from memory.  I haven't revisted this model much since I 
developed my first one late last year.  Maybe they're some new knobs which
make it even easier.
