Let's say: NEED NOT jeopardize privacy. If the later octets are de facto allocated in a pattern that typically maps to a finer-grain location (for example, to the level of a particular city block or a particular WiFi network in a store) then that would reveal too much, given the way public policy is going. Perhaps you could add text saying that the later octets must not reflect geographic location. _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
