Sure, and just because the x86 instruction set works for desktop PCs, it doesn't mean it works well for cellphones. Which was exactly my point: It will spread because of incentives, not because it's the "better" solution. And if another solution works well enough and is cheaper to implement, it will slow the adoption of IPv6.
