Removing a cost and an artificial shortage may cause many innovative things to happen. History is full of examples when lower costs and higher availability of something have caused a burst of innovation. What I meant in the grandparent comment is that if a company makes it their business strategy to have all devices call home, they will do that regardless if they use ipv4 or ipv6. But if ipv6 is widely implemented and there is no cost to ip addresses, it is entirely possible that another company can create an ap that allows you to directly communicate to your devices without using a central server.
