I regret that I do not have time these days to read through more than 
your short version, but I generally agree with your design assumption.  
This is not to say that I don't hope for better.  DHCP prefix delegation 
is a good step in the right direction, particularly for SMB & home 
networks.  I've consistently said that our scaling problem is NOT with 
enterprise networks, but with home and personal networks.  In those 
latter two cases I hold out more hope.  If enterprise networks were 
merely a 2^6 exception, we would be in good shape.
