On September 14th Downhill Battle wants you to call Congress to let your representatives know your views on the Inducing Infringement of Copyrights Act (IICA, née INDUCE Act): SaveBetamax.org:

The Betamax ruling is the only thing that protects your right to own a VCR, tape recorder, CD-burner, DVD-burner, iPod, or TiVo. It's that important. But new legislation that's being pushed through the Senate by lobbyists for the music and movie industries would override the Betamax decision and create a huge liability for any business that makes products which can copy sound or video. This legislation (formerly known as the INDUCE Act) would essentially give Hollywood veto power over a huge range of new technologies. And if they get this power, they'll definitely use it: just as they tried to stomp out the VCR in the 70's and 80's, the music and movie industries want to force all content to go through their own restricted channels.
