But we have 2 classes of users - those who will use these new bandwidth intensive apps and those who won't. Under the content providers pay model, only the intensive users will pay. Under the network providers pay model, everyone pays - even those who only do email and regular browsing. The content providers pay model is fairer to the majority of the users. Though the biggest heaviest users will complain when they have to carry more of the costs they are causing.
Maybe the network providers(ISPs) will have to move to a bytes/mo model instead of flat rates. That way the content providers won't pay extra and the end users will pay based upon how much bandwidth they consume.
And your second example ("per byte" pricing) is how it SHOULD work. This most closely matches the "cost causer" with the "cost bearer" and doesn't send the mixed economic signals that running the charge through a third party (the content provider) does.
