   Well, it's a case of is it worth the effort?  First a few facts.   
      
   1.  Both ends of the tunnel are on the same ISP.   
      
   2.  This ISP is one where they communicate well with users, and they don't   
   assume users are ignorant of tech issues.  In fact, they probably have the   
   highest proportion of tech savvy users of any ISP.  Therefore, any such change   
   in the future is likely to be well communicated.  They are also likely to keep   
   dual stack going as long as feasible.   
      
   3.  This also requires liaison with the group running the other end of the   
   tunnel.   
      
   Liklihood is it's far enough in the future that one or both ends will see a   
   generational change of hardware, and there will be a more compelling reason to   
   upgrade and change things around other than "because I can" or "future   
   proofing", and that time is going to be a better time to make the change. :)

   True.   
      
    MvV> IPv6 is the future. IPv4 is broke, let's get rid of it. ;-)   
      
    TL> ... I give up, what is the meaning of life?

   Haha, there's always someone. :D
