I've said before that I think the industry has to move to a per MB business model. It just does not make any sense that casual users of Comcast HSI pay the same amount as heavy user. I'm a heavy user, so I would certainly be negatively affected, but when I see Comcast and others talking about implementing a "surcharge" to certain companies (i.e. Google) so that their traffic is "prioritized" then I start to get nervous because you open up a whole can of worms regarding funny business between Comcast and some website (Comcast has no fear of blacking out cable channels if they cannot get a good deal from the content provider).
