The Nation has a editorial against RFID focusing mostly on the privacy issue. Come to think of it the privacy issue is the only real issue of concern about RFID. In the piece Simson L. Garfinkel calls for some sort of voluntary controls on the use of RFID and if we find these voluntary controls don't work then we call for something with some teeth. Garfinkel provides a link to the RFID Privacy Workshop @ MIT that took place back in November but has a blog of sorts that still seems active (lots of posts for January).
