Of course not.  Based on history I would expect a killer application to appear when we hit 10% Internet traffic penetration.  That will constitute enough of an audience to attract developer attention.  I'm guessing this is around 2014.

True, but firewalls are much easier to configure than NAT.  As someone who does network/security consulting and teaching for a living I can tell you that most people struggle with NAT but not with firewall rules.

It is a little bit of the chicken and egg problem, but really IPv6 is the area code problem.  What do you do in the telephone system when a region/country runs out of area codes?  You have to expand the address system.  Ask anyone outside of IT if they would be willing to put their neighborhood behind a PBX to preclude expanding the addressing system and they'll laugh at you.  They would never accept such a change.  In order to support Internet growth and facilitate easy communication (the point of networking and IP!) we need IPv6.
