Are we talking about charging for access or for content/service? It is important to separate these two even if operators so far with the limited possibilities of mobile devices (non-Internet connected) have controlled both. For content it is of course desirable to charge for what is delivered, which is not a problem when performed on the application layer. However, it is impossible (and completely use-less) to try to charge different for the access bit-pipe depending on content transmitted. The network can and should not know what the bits transmitted are. "Snooping" may give the network a clue about what the application data transmitted is, but it can never tell for sure. Further on, with end2end security this possibility is completely eliminated.
