Incidentally, this doesn't apply to Africa today, because 
AFRINIC still have lots of IPv4 space to feed any new 
entrant to their heart's content.

I have mates in Asia-Pac, North America and Europe that will 
be the ones sweating if they are a new start-up.

A friend recently started a mobile operation in Malaysia two 
years ago. You can imagine the problem they are having 
rolling out and scaling their 3G/3G data service.

And if AFRINIC do run out of their IPv4 space, I can almost 
guarantee you that any new start-ups in Africa will NOT be 
able to have "IPv4 acquisition" line items in their budget.

Users won't complain until the CGN starts to do bad things 
to their traffic, like run out of Layer 4 ports per IP 
address due to increasing connectedness of applications, add 
delay to applications getting network, CGN failure, traffic 
tromboning e.t.c.

Operators of CGN's will cry at some point. It's different 
for different operators, as some are happy throwing millions 
of CGN $$ at the problem.
