Here's a sketch: A is behind a firewall, or has a rapidly changing dynamic IP (for some defined values of 'rapidly'), and wants to advertise the correct IP address.
A asks B for its IP (details on when and how to ask not yet determined but almost certainly related to connection attempts from A to B) B replies with "your address is aaa.bbb.ccc.ddd" A generates a random public/private pair A's "self" servlet generates a webpage containing the message "Self" encoded using the private key A tries connecting to http://aaa.bbb.ccc.ddd/ppppp/servlet/self and decoding the result using the private key to see if the message is Self. If it is, A knows it can reach itself on the IP address B told it, and doesn't even need to trust node B.
