The problem is "get content dual-stacked".

Somebody made this handy page of the IPv6 status for the Alexa Top 500.

Awful lot of red spots even in the top 100.  Hell, even amazon.com
isn't IPv6 yet.  And the long tail is going to be the death of a thousand
cuts for the call center unless you have a way to deal with those sites.

And the devil is in the details.  cnn.com itself has a quad-A. But looking
at Chrome loading it with the IPvFoo extension, I see that of the 145
addresses it hits, only 38 are IPv6, the rest are IPv4.

On the other hand, looking at *who* are the IPv4, they seem to be
overwhelmingly ad servers and analytics sites - so maybe hitting cnn.com as
IPv6-only is a win for the consumer.  I rather suspect that the CFO of CNN
would see it differently though....

(Eerily reminiscent of the factoid that 60% of the cost of a long distance
phone call before the AT&T breakup was keeping the accounting records
so they could bill the customer)
