Incidentally, this doesn't apply to Africa today, because=20
AFRINIC still have lots of IPv4 space to feed any new=20

I have mates in Asia-Pac, North America and Europe that will=20
be the ones sweating if they are a new start-up.
A friend recently started a mobile operation in Malaysia two=20
years ago. You can imagine the problem they are having=20
rolling out and scaling their 3G/3G data service.
And if AFRINIC do run out of their IPv4 space, I can almost=20
guarantee you that any new start-ups in Africa will NOT be=20
able to have "IPv4 acquisition" line items in their budget.

Users won't complain until the CGN starts to do bad things=20
to their traffic, like run out of Layer 4 ports per IP=20
address due to increasing connectedness of applications, add=20
delay to applications getting network, CGN failure, traffic=20
tromboning e.t.c.
Operators of CGN's will cry at some point. It's different=20
for different operators, as some are happy throwing millions=20
of CGN $$ at the problem.
