"That's unacceptable for certain applications." I'm confused: Can you provide a few examples of such applications?

Please consider the following case: A self-organizing peer-to-peer overlay which exchanges peer address information via encrypted network links. Peers in the swarm can see that data, but passive third-party observers cannot except by observing the traffic exchanged from peers they can see, which will only represent a small fraction of the IP addresses in use by a large swarm. Sending that data in the clear to the ISP in order for it to be ranked now reveals many addresses which the peer might never connect to to that passive observer. That's unacceptable for certain applications. In some cases, the user might trust their ISP with that data but still not want it to be exposed as plaintext traffic on the wire.
