Rep. Ed Markey (D-MA) and Chip Pickering (R-MS) have introduced the Internet Freedom Preservation Act of 2008 (H.R. 5353) in the House.
Here's an excerpt from the press release:
The goal of this bipartisan legislation is to assure consumers, content providers, and high tech innovators that the historic, open architecture nature of the Internet will be preserved and fostered. H.R. 5353 is designed to assess and promote Internet freedom for consumers and content providers. Internet freedom generally embodies the notion that consumers and content providers should be free to send, receive, access and use the lawful applications, content, and services of their choice on broadband networks, possess the effective right to attach and use non-harmful devices to use in conjunction with their broadband services, and that content providers not be subjected to unreasonably discriminatory practices by broadband network providers.
