Here's an article about the bandwidth metering from the New York Times. I particularly like:
The Time Warner plan has the potential to bring Internet use full circle, back to the days when pay-as-you-go pricing held back the Web’s popularity. In the early days of dial-up access, America Online and other providers offered tiered pricing, in part because audio and video were barely viable online. Consumers feared going over their allotted time and bristled at the idea that access to cyberspace was billed by the hour.
The more things change the more they stay the same. The carriers may be relegated to selling "dumb pipes" but they're pretty "smart" at making money with them.
