(Sorry for the top-post...I'm mobile atm.)

My understanding is that core network operators filter ASs for which they
don't have a contract for transit. I.e, if I were to get my own PI space,
I'd have to pay tier 1 networks (or pay someone to ride on *their*
contract) for a contract to have packets destined for my AS to be able to
reach me across their network.
