All we are talking about here is how you differentiate the cost of service, for different categories of subscribers." Yes, I agree that differentiating services can be a positive thing. No, I do not think Comcast is going about it the right way. In fact, the way they are doing it is suspect and points to a different motive. Any Comcast executives out there that can enlighten us? Dan
