I think this document isn't ready for IETF last call. I think the context of an experimental assignment which heads to distributing IPv6 addresses to end-entities, even if the experiment is not intended to be globally routable, poses questions about how the address management function is going to work. Can the working group be asked to discuss how this is meant to be interpreted in the light of RFC2050 based processes? It might avoid future pain if its clear how the IAB and the RIR understand these addresses and their management. The experiment has all the attributes of a general, wide-ranging address distribution and management activity. I haven't seen any substantive discussion of this in the WG mailing lists, and I'm worried this hasn't been documented, or understood. cheers -George
