Once the network gets big enough so that each node and client doesnt
know all the nodes ip addresses, is there a compelling reason that ip
addresses of relays which are non-exit and non-guard need to be
published to the outside world at all?  Then if someone ran a Tor node
just to leak node ip addresses, it might be easy to figure out who it
was and drop them from the network, and they would at least be
contributing bandwidth.
