They've been talking about this on This Week in Tech for several weeks now.
That said, online petitions are a complete waste of time. Any time someone says, "Please sign my Web-based petition, I politely find a way to change the conversation." They simply don't work, no matter how many signatures you get, because the vast majority of Congress has no idea how the Internet works. They also tend to be able to avoid it altogether, and will never see your petition. No news agencies will pick it up, either. Also, it's simply too easy to get a thousand signatures from people who don't even exist. Petitions work at the local level (and we are talking about pen and paper petitions), because the names can be verified and the addresses are known to the local government officials.
I'm only saying this because your time, if you really care about certain issues, is better spent making a few phone calls, and trying to get others to make a few phone calls. If you want to throw up a Web site, go ahead, and you can drive people to it, but it's much easier to try to direct people toward a site that already exists and already supports your ideas. I would check out the EFF (eff.org) Web site to see if they have something on this. Driving people to their site ensures that everyone can access similar information, and the EFF is good about telling you which member of Congress you can call and complain to.
