If home automation systems become more commonplace, having a "server" at home may also become more commonplace. What's the point of having an IPv6-enabled lightbulb if you can't turn it off from half-way around the world? But as long as DNS updates dynamically, this shouldn't be a problem. For organizations renumbering is more painful, but as long as there's plenty of time to prepare - it should be manageable. If it's too painful, there are provider independent addresses, but how many really need them? Yoav
