IMO, this will not be a decision made by ICANN or a network provider. This will be made by a platform/OS company.

Basically, once IPv6 is presumed ubiquitous (it doesn't have to be actually ubiquitous) -- just if you can't reach 
something by IPv6 you assume it's the far-side's problem -- IPv4 becomes a relic from a business point-of-view, because 
anyone who doesn't support it is not presumed to be at fault. 

Microsoft, Apple, or gee-whiz-new-gadget guy simply has to come out with the next revision of their killer product that 
has dropped support for it. Many may complain, but with those that have sufficient market power to not see a 
significant affect (and can justify retasking their internal development resources who no longer have to regression 
test IPv4 stuff against any perceived customer loss) will do it -- they'll probably call it an upgrade. 

It's been done before. It'll happen again. 

This doesn't mean IPv4 will disappear. Just like the 20+ year old machines that are still on the net via IPv4 -> legacy 
protocol gateways, pockets of IPv4 may exist for decades via similar devices -- but at that point, we just dismiss 
those guys as crackpots.

Anyone have an IPv6 coke machine yet?
