This is simply accomodated by mutliplying the maximum utilisation figure by 
0.75 for every layer of hierarchy or aggregation in the network. So for
a 3 layer network plus another layer for international aggregation the
maximum utilisation falls to 0.75^4=0.316 == 32%.

This is the theoritical maximum address utilisation that can be achieved 
without breaking aggregates. 

I think we should penalize anyone who gets a better address utilisation than 
this because they are obviously announcing more routes than they need to ;-)
