What about netflow ?

You can do traffic analysis based on statistical sampling. Good luck doing _billing_ based on statistics. In any case, nobody was able to connect backbone flow traces for any significant amount of time. A typical Internet load on OC-3 would produce about 7000 fps, or 500 mil flows per day. Now, crunching that data to generate bills is going to be fun. I'm not saying this is impossible, but the infrastructure for doing so is going to cost at least an order of magnitude more than the non-accounting backbone. --vadim
