I still think that needs-based allocation is antiquated IPv4 thinking.  What does it matter if someone gets some IPv6 space they don't need right now?  Would it be a bad thing if every household in the world got a /48 just because they wanted to?  Even if they are a single homed so what? 

The world may need to figure out how to route all those /48's, but that is not for ARIN to dictate.  When it becomes a reality the world will figure out a way to make it work.  Do I have all the answers right now?  Of course not.  Do I trust human ingenuity to figure it out?  Of course I do.
