If you found my recent post on Public Access PCs Booby-Trapped of any use, you may also find a follow-up article by SC Magazine's Dan Raywood of interest.
The article on Keyloggers found plugged into library computers quotes some further thoughts I sent him in a subsequent exchange of email, and also quotes Wilmslow police inspector Matt Welsted and F-Secure's Sean Sullivan.
