Hello! Quite interesting discussion you have!

Think about Cable. It's easy there - you have a modem with one or more Ethernet ports. Some RA announcements for the customers /64 and everyone is happy. Think about the advantage of "two computers when using IPv4 and an infinite amount of computers when using IPv6 for only 29.95 per month". What a motivation for the customer to use it ;-) Of course all the "Router / Blackbox Firewall" users are lost. ADSL is a bit more problematic. Standard ppp handles just the link layer addresses. Who should get the /64? The ppp endpoint itself or the network behind? Apple for example goes the simple way and passes all the configuration to the user. ppp devices won't accept RA announcements. How does Windows behave? I don't now. Next point: DNS. DHCPv6 is IMHO only supported by some Linux distros. Apple once again uses the DNS configured by IPv4 DHCP or manually configured ones. Windows has some site wide addresses out of a deprecated space predefined (fec0:0:0:ffff::1~3). The approach to pack DNS IPs into RA is yet too young and not standardized or even implemented. So we have still a lot of work in front of us. Even more work will come for small and medium business networks. Today there is a NAT gatway in front of the network and tunneling VPN for the remote workers or office interconnect. There is usually an internal DNS (Windows AD) carrying the local addresses. Everyone knows the basics and how to set up such environemnts. What about the future? Route IPv6 directly to the clients? What about remote workers? Delegate the reverse and forward lookup to the internal DNS? Of course all those questions are answered when you operate an open network. Like universities or ISPs usually do. Or when you run an independend company network only connected by proxies. But for other usage, like SOHO users, there are still open points.
