If you did polynomial approximation, what are your numbers? Or do you 
believe it to be  exponential growth? Have you compared estimates &
grown on per-region (RIR) basis?

BTW - Personally I think even Geoff numbers are couple years ahead of
when runout will actually happen (depending on how you define runout).
But I'm not sure 1-3 year difference and exact year in projection is 
really that important, event will happen in next decade anyway and 
everyone should know and be preparing for it.

Maybe its for the good. When time runs out is when people start to
react, its just important to be ready and have all current computers,
OS and network equipment suporting v6 (even if its not configured).
The last one is however the one I'm most worried about - there are
way too many personal routers & NAT devices out there and most are
not capable of handling ipv6 and many do not know how to update them
even if software were to be available.
