I realize that 99% of people using IPv6 today at home have static IPs with tunnel brokers, but if it ever gets rolled out mainstrem it is likely to involve dynamic prefixes, which means anytime your ISP changes your outside IP every device in your house will change its internet-routable IP. Today you don't see that since everybody uses NAT. Link-local is really the solution to this if you don't want to use NAT in the IPv6 world (which is clearly the greater evil, and even then you're using link local anyway). -- Rich
