I don't think its a good idea, next cable companies will be charging you for how many hours of TV you watch, after all that draws bandwidth too...bad enough the MLB channel can rarely go 2 minutes without a " freeze "
Cable and broadband ISO's should just bite the bullet on this one
as a wise man once said " it's bullsh*t and it's bad for you "
Nah, it won't work that way. What Comcast and their ilk are trying to do is steer you toward their services and content, and away from competitors. Classic monopolist behavior, but apparently no one's going to do anything about it.
So, you can watch all the Comcast TV you want never hit a cap, and you can use their Fancast service without penalty, but if you decide to go and use Netflix, well, that's gonna count against your cap.
All the cable/Internet providers seem to be going this way: use our services, which are faster and don't count toward your cap; or use competitors and risk overage charges!
