Cable companies have enjoyed the upper hand in ISP control for a long time. Things like this (along with fiber and IPTV) are going to drag them from their high:
Comcast has punished some transgressors by cutting off their Internet service, arguing that excessive downloaders hog Internet capacity and slow down the network for other customers. The company declines to reveal its download limits.It's their prerogative, and I'm sure there's something in the monthly contract stipulating a download limit. But it's stupid of them.
Bandwidth crunch is inevitable but punishing high end users isn't going to bring any more business.
Personally I can't wait to live in a house that has fiber and IPTV so I can say goodbye to Warner / TimeWarner / Comcast forever. It's been long enough!
