The Senate Committe on Commerce, Science and Transportation is considering ammending the 1996 telecomunications act in the states to end “network neutrality”. This would allow telcos to charge you a different rate depending on the kinds of things you do on the net. Eg. Pay more if you’re using VoIP or filesharing.
I talked about the VoIP thing in this article: Why iTalk?
Bill Thompson talks more about, Why the net should stay neutral on his BBC blog.
