Under IPv6, won't customers just need a hub or a switch? Every IPv6-aware device in the home will just request a unique address directly from the ISP, completely eliminating the need for home routers. Of course, devices still needing IPv4 would need some other solution.
Of course, that doesn't come without a tradeoff (as mentioned in the submission). Those IPv6 devices will need to be aware that they are connected to the Internet at large, and security will need to be addressed accordingly.
