We can already do dual stack - that's not really a problem.  I was 
really rather hoping to avoid the giant NAT box.  I'll take a look at DS 
Lite and or NAT64/DNS64 and see if that makes any sense.

Dual stack isn't all that hard to deploy in the enterprise, perhaps even 
IPv6 only with NAT for backward compatibility.

Running dual stack to residential consumers still has huge issues with 
CPE.  It's not an environment where we have control over the router the 
customer picks up at Walmart.   There is really very little point in 
spending a lot of resources on something the consumer can't currently 
use.  I don't think saying we missed the boat really applies - and the 
consumer CPE ship is sinking at the dock.
