> It's easy to live without IPv6 until someone creates the IPv6-only killer app This was a few years ago, but the majority of Danish ISP wasn't offering IPv6, because "there's is no demand from customers". Well, the customers also aren't demanding IPv4, they are demanding internet access. How you deliver it is not interesting to anyone but a small niche segment of the market. If you could somehow make it work over IPX, then 95% of customers would be fine with that, it's not something they care about.
