No doubt this will be discussed in the next call, but...
With respect to the emails from Messrs Roy and Toga, can someone please explain to me why inter-administrative-domain communication and inter-zonal communication within an administrative domain require separate consideration? Mr Roy's email appears to accept that when things come down to actual messages (section 1.5), the same information requires communication. Given that everybody appears to be agreed that the smallest possible administrative domain is a single zone, and that nobody appears to want to exclude the possibility of having some sort of hierachy, I fail to see why we need to do any more than define communication between administrative domains and remember that zones are degenerate administrative domains. If I've missed something fundamental, please tell me!
