This is basically what Amazon is planning to launch with the KDK. Amazon's model is fixed price per app, not bandwidth based. Since 3G is free with the device, apps that need bandwidth need to have a subscription price to use the network. Amazon takes some, you get some. Presumably, Amazon uses this to offset 3G costs or pays it to the carrier.
