I'm sorry, but I'm a bit confused by this apparent contradiction.   
Are you approaching IPv6 from the perspective that it is going to  
allow us to deploy IP stacks on hundreds of new devices per home, and  
per person, or are you approaching it from the perspective that IPv6  
is just meant to give us breathing room in our deployment of current  
applications of IPv4?  If the former, then I don't understand how you  
can question that the potential exists for us to use up a significant  
chunk of the v6 space in the next 60 years.
