If there are, say, 250-500 million broadband services in the world 
(probably more) then, if every ISP followed best practise for IPv6 
address allocation, (sparse, bits for infrastructure, whatever etc) then 
what percentage of the space do we have left if we hand out /56 or 
/48s?).  Taking into account the space already carved off for link 
local, private addressing, US Military etc.

Has anyone done some analysis of what this might look like?  Especially 
with growth etc.
