Enterprise CIOs, or ISP architects?  They have different problems with IPv6.

ISPs will break IPv4 for their paying customers, and charge to put it back
together?    Brilliant!
Especially if the guy down the street hasn't broken it yet.[1]

How do you align those costs?
If IPv6 requires a new home gateway but IPv4 only requires part of a CGN, 
which is cheaper?  Who incurs the cost? [2] 

If IPv6 doesn't require a new home gateway, but only gets you to 50% of 
the Internet, which is cheaper?  Answer:  both is cheaper than one or the
other:  use CGN for IPv4-only traffic (so you don't lose customers, except
the stuff CGN breaks), use native IPv6 where possible (so you don't pay
for their CGN).  Cap and grow if you can.

Bonus questions:  What applications does your CGN break?  Are you using
CGN, dual-stack light, A+P, or portrange?  When will you need this in your
network, how long will it take to test it, and how long will it take to build the
provisioning and operational systems around it?


[1]  Notice whether IPv4 is broken for existing customers or only new
customers.  What happens to competition if users can't switch providers
and receive a comparable IPv4 service?
[2]  Important question.  Also important is, "Who are they paying, and what
does their ROI look like?"  Are CPE vendors thinking, "If I don't support
IPv6 until 2012, then all my consumers will have to buy new gear from me
again when they're forced into IPv6"?
