How is this cost any higher than that of deploying IPv6?  It seems to  
me that there's no significant qualitative cost differentiation  
between deploying v6 as it stands today and some better solution.  In  
fact, a better solution might well be easier to deploy, as the cost/ 
benefit ratio might be tolerable.
