That situation will not last very long! We'll see more and more IPv6-only 
networks, since all IPv4 addresses will be assigned soon. Users will 
complain that they can't reach the webshop or B2B site of a new company. 
So nearly any network is forced to support IPv6 sooner or later.

As I wrote above: connectivity is more important than security (for 
users)! IPv6 won't be an option, it's becoming a requirement. It's not our 
decision because the market is heading to IPv6. We may advise how to 
improve security but nothing more.

So any discussions about deploying IPv6 or not are futile IMHO.
