RFID has a range of no more than 3 or 4 feet. It's not a "tracking mechanism" and anyone who tells you it is is a few bubbles off of plum.

Parents Protest School Mandate That Students Wear Radio ID Tags

The link to the thread you provided, Parents Protest School Mandate That Students Wear Radio ID Tags , should help you understand.  You can't track the RFID tags from a distance, only when they pass within a few feet of a reader.  All it will tell you is that the RFID tag passed a given spot.  It's like putting a video camera on a doorway.

It's not a tracking mechanism for a person.  It's more a turnstile gate for a doorway, or some similar access point.  Same thing happens when you pass your authorized badge over the reader on a secure building.

I did, however, really spook some of my coworkers.  We had cell phone antenna boosters installed by Cingular in our data center (reception was awful).  The antennas were little domes, about 4 inches across and 6 inches high, attached to the ceiling in the hallway in pairs about a foot apart.  We have access badges for the building and I told a few folks that the antennas were to allow management to track us.  Several of them believed me.

I don't have much patience for folks who don't understand technology and freak out about the wrong things.  It is fun, however, to play with a Luddites head some.
