The House Committee on the Judiciary today approved the Internet Freedom and Nondiscrimination Act (HR 5417) in a vote of 20-12. This particular 'Net neutrality bill would make it an antitrust violation to "block impair, discriminate or interfere with anyone’s services or applications or content," but the bill also addresses service improvements on top of the status quo. If a provider were to offer increase VoIP performance, for instance, the bill would require such providers to prioritize or offer enhanced quality of service "to all data of that type... without imposing a surcharge or other consideration for such prioritization or enhances quality of service."
This bill will die very quickly, I think. I'd like to be optimistic, but I just don't see something like this having any chance of passing.
