This seems to be a good bill ...http://www.theregister.co.uk/2012/12/21/sentator_wyden_data_cap_bill/
Senator Ron Wyden has introduced the Data Cap Integrity Act, which will limit the amount of capping ISPs can do and give consumers a clear idea of how much data they are using and what they are being charged for.
The bill calls for the FCC to make sure ISPs tell consumers the cost of their data, give an accurate up and download speed, and make plain when data is being throttled or managed. The FCC will also get the power to remove data caps if it determines they aren't in place for traffic-management purposes.
The move comes only days after a report into data capping from the non-partisan New America Foundation think-tank. The detailed study concluded that data caps are ineffective at traffic management and are being used by ISPs to increase profits and lock down markets, and aren't growing to reflect greater internet use.
This representative is standing out from all other US politicians for his simple and transparent view of tech issues that affect Americans and his clear cut Bill is well worth backing in my opinion.
