We've started playing with Stateful NAT64 on a couple of 
Cisco ASR1006's. 

In general, it works okay, save for issues with applications 
that have no IPv6 support, e.g., Skype, e.t.c. We hope to 
find more issues as more customers sign up to be guinea

Indeed. We're doing what we can to be part of the solution, 
by picking technologies we think will be useful for us and 
going out and testing them at scale, with a goal to start 
rolling out v6 in droves as well provide usable operator 
feedback re: our deployment to vendors and other operators 

As much as we'd like to see how the market unravels re: v4, 
e.t.c., the fact remains that v6 is the inevitable solution. 
So best to get cracking now with real deployments.
