I live in DC and the Eastern Corridore Amtrak lines are really awesome. By car it takes 5-8 hours to get to NYC depending on traffic. Amtrak takes 3.5 hours. This is the busiest route on Amtrak as far as I know, and it would be great if it had a dedicated high speed track.
I think the reason for the pricing at ~$2.00 GB is that it makes the bandwidth price for a Netflix or other streaming movie about equal with your standard cable On-Demand movie. If the ISP, which also is a cable company, owns the On-Demand rights to content also available to streaming, it seems very likely that they would want to find a way to keep people watching their $4-$8 movies when they are "free" with an $8 Netflix subscription.
