actually, its pretty clear.
peer - exchange routes with a neighbor (BGP/OSPF/ISIS/EGP/Static).
transit - your neighbor agrees to send your routes to -their- neighbors.
peering you can control, transit is controlled by a third party.
so Jack, you could pay Sprint for transit (they propogte your routes elsewhere) and
then insist on no-export for the routes you give them.. -IF- Sprint honours your
no-export, then your just peering, regardless of what you are paying for.
