[Toboe]

Do you mean net neutral pay-for-what-you-use?

I.e.

You can buy 5GB volume. Everything you do counts against it.

Or do you mean selective pay-for-what-you-use-and-your-ISP-doesn't-prefer?

I.e.

You can buy 5GB, the ISP chooses what does and doesn't count against that.

From NN point of view: The former is fine. The latter isn't. (The whole king-maker problems)
