Paper Show Digital Bluetooth Pen For Real-Time Annotation

We've seen digital pens before, and we've been pestered by PR people desperate to convince us that their digital pen is the best yet, but this is the first time I've seen a PR person talk up another person's product.  The PR in question is Drew Benvie, and the pen is the Paper Show; a cordless stylus with a USB Bluetooth dongle and actual ink, it relies on specially-encoded paper to control presentations and write on-screen in real-time.

Paper is made in A4 and A3 pads for note-taking and presentation use, and there's also standard printer paper with the encoding pattern.  That lets you print off notes or other documents, mark them up using the Paper Show pen, and have that automatically tracked and annotated on the electronic version.

The USB key holds the Paper Show software, and the company makes it sound like you need it even if your computer already has Bluetooth.  At the moment it's PC-only, too.  As an ex-Tablet PC user I'm always curious about these pens, so I'm hoping we can get one in to look over ourselves.
