Interesting. The UW RFID project reminded me of Steve Mann's work with cameras, particularly his concept of sousveillance. I think there is a quite a bit of good use to be had with RFID tags, especially for a plastic tag you could put on luggage, or other shipping issues. I'm glad they conducted this study, there is some scholarship on what the effect of privacy might be in a "web of things" but scientific-ish research is always nice to pull out to bolster your argument when these issues are being legislated on.
