If you look a bit more carefully, you will find that registering for 0/0 doesn’t work without a bit more smartness in the ABR. It’s doable, but not yet in the text. As it stands right now, the PE’s COULD register for the summaries of the other areas. That would decrease the number of registrations. How the PE learns what those summaries are is currently magic. At the end of the day, I don’t think that scale discussions will resolve this. In fact, if the cost of deployment was actually zero, I doubt that we would still see any progress in this conversation. How do we depolarize this? Tony
