They scale fine, but there is a point beyond which adding additional peers to the overlay routing merely adds latency. Don't have time to look up the references now, but there are a number of papers discussing the advantages of different numbers of peers (superpeers in a lot of systems) needed for overlay routing. You don't need 10M.
