Before focusing on the numbering plan, you might want to wrestle with the "service model" issues. Some people want a pure end-to-end system, other people (like me) advocate a proxy/gateway model. IPv6 is a product of the end-to-end group and IPv8 is a product of the proxy/gateway advocates, who some like to label "telephone people". In the end-to-end model the assumption is that a "telephone" will have enough intelligence to communicate directly with other telephones and servers attached to the open and flat network. In the proxy/gateway model the telephone has an uplink connection to a machine that provides agency services via software agents. Those agencies then cooperate and have a different trust relationship with each other than end-users. Some people do not like giving away that trust relationship. Therefore, they advocate end-to-end. It will be interesting to see where it all comes out. Fortunately, the marketplace will get to decide...if it is allowed to... - Jim Fleming Unir Corporation IBC, Tortola, BVI
