A number of people suggested to Comcast that they'd be best served by a user-based traffic accounting and management system, and you were certainly one of them. It seems that it took them as long as it did simply because they had to find some gear that would interface with the existing infrastructure in the right way to pull it off. At the heart of it, the cable CMTS needs to make decisions in microseconds in response to bnadwidth requests from customer modems, and it takes very specialized gear to do that.
And it's not done yet, as the new scheme is simply being lab-tested at this point, and it will have to be field-tested before large-scale rollout. When you've got tens of millions of customers in your network, you can't exactly turn on a dime.
