Assuming you mean a pay-as-you-use scheme that merely charges a modest premium over the traditional model of paying up front, it's tough to see why it would be attractive for a provider. What their cost for the hardware or bandwidth happens to be wouldn't make much difference, since they have to pay it regardless. A pay-as-you-use scheme that charges a huge premium, such as a multiple of the providers cost, on the other hand, could be quite attractive, as evidenced by what cloud providers do.
