Yup. It is the problem. Except that at some point your ISP will be
unable to give you a v4 address at all and then the ISP would have a
very serious business crisis on it's hands. If the ISP were looking
ahead then it would understand that eating the cost of v6 rollout to
customers, who are not demanding it but it "just works", would be in
their best long term business interests. When they get to the point
where they cannot hand out a v4 address to go with the v6, if the rest
of the net has reached that magic number, then the customer still won't
notice.

Of course, but we all know it's not possible to continue handing out v4
addresses.

Agreed. A v6 only killer app would go a long way to helping this.
