It's All About Safety
From a /. entry comes this story from ZDNet.
For the safety of the American people, the government wants to require that they can track the location of all VoIP handsets that connect to the public telephone network. They want to map all wireless access points in the United States (a nearly impossible feat) so they can triangulate signals from VoIP callers.
Yes, our benevolent government just wants to be sure that we can all call 911 no matter where we are and get a response. They won't use this power to track us for non-emergency purposes. They won't abuse this power or use it against us. No, that couldn't happen.
This is coming from the FCC under the Bush administration. Still think he's a conservative?
