Agreed, IPv4 will be here a long time, because, not one company will risk
financial loses and stock devaluation over address space. The day that a
large company flips to IPv6 only in an IPv4 world will be the day to short
as many shares of that stock as possible.

This creates the big market for IPv4. Costs price per IP address must get
beyond the price of a good lunch once per month. Because, that's an amount
that businesses understand and begin to pay attention. IPv4 address space
is now a profit center and will cost more to the end user than transit and
network costs... Or... how will IPv6 catch on in any other way ?
