The reason why the internet hasn't completely collapsed by now (with half of the nodes being PC drones) are the use of firewalls&NATs to seperate "internal" networks from the internet, be it home, organizational or governmental. Try to convince folks to completely remove all outside doors, windows, window gates, curtain, blinds, flyscreens from their home to "leverage" many convenient un-restricted openings to the interior of the house. I doubt you mind a lot of followers, and some of those who do might quickly and painfully find out that the original access scheme to their house did have a few non-marginal advantages for life, limb and property. If your plan is to further delay IPv6 as long as possible, then making it dependent on unrestricted end-to-end IPv6 connectivity might be the most reliable approach to ensure the maximum pain and resistance. -Martin _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
