I think we'll have a "double S". Almost all residential broadband providers
here (.fi) have changed their policy from allocating 10/8 addresses and
NATting the tens of thousands of subscribers to the outside to automatically
allocating public IP's with DHCP. Total consumption in order of a few
hundred thousand addresses for our small country alone.

Private address space is a pain if you have to redo company boundaries.
Merging two or three businesses who all used the first subnets of 10/8
takes a lot of unneccessary extra hardware.
