None of this will be news to you, but I am going to post it anyway.
The industry will find it very difficult to switch to a metered market for corporate America (especially those with secure, end to end, networks), but I could see it happening for home use. Many ISPs feel that they have sold one thing, only to have that thing manipulated over time. In other words,
they felt that they sold a data connection, and now that connection streams a whole lot more content than data. An example - my cable provider sells me a data circuit, and I use it for everything, including voice. With the advent of free VoIP solutions, my cable company is no longer able to charge me for a phone, and it galls them. They want to get paid for that type of content, and the government is saying that they can't. Their only option is to change the way that they price their goods. If they do as bicker has suggested (which would only be a decision to follow the lead of wireless providers), they will stop selling bandwidth and start selling metered data transmission.
