What we tried for our experiment was simple: you turn in your RFID card at the
end of the meeting, and it is randomly re-used for the next one, i.e., a new
number is assigned each meeting. Unfortunately, we only got a relatively small
fraction of RFID badges back, if I recall correctly, as people presumably
forgot to turn them in.

Likewise. The point being, handing everyone in IETF an RFID tag probably
doesn't have new privacy implications for most of them, and giving them a
faraday cage, as was done in Hiroshima, addresses the remaining implications
for those people who do not carry powered-on cell phones or laptops for
privacy reasons. If you carry a powered on cell phone, I don't think you
can argue that carrying an RFID tag with a simple number in it makes things
any worse.
Actually, the main argument I'd make against IETF RFID tags is that it's more
plastic to throw out.
