AOL's Book Maven points to the Long Pen, a bulky but cool gadget that allows authors to sign books remotely.

The Long Pen consists of three "stations," if you will: the author has a video monitor and an electronic pad with a stylus, and so does the reader. Let's put the author in New York, and the reader in, say, Zagreb. These stations are connected via a dedicated Internet cable, and the "go-between" is a metal contraption on the readers' side that clamps and holds a regular pen (it can be any pen -- Sharpie, ballpoint, the reader's own heirloom Montblanc) that is then manipulated by signals from the author's station to reproduce signature, inscription -- even doodles.
