[warning sub-operational]
what's cool is that andre found that there
is some natural `tiering' of ASes just according
to (almost any topological) quantitative connectivity metrics

(math-heavy, no ASes identified, just illustrates that 
tiering has some sense manifested in real data, 
which i think is pretty cool)
