Linux USB-Driver: initial release of vp-usb-lock
Tim 'pez2001' Theede writes "vp-usb-lock is a Linux kernel driver and PAM module that utilizes the PC wireless USB lock and makes it possible to use it as authentication method for your Linux box. It is easy to install, but needs access to the sources of the kernel and PAM to build correctly. It has been tested under Fedora Core 2 with a custom made 2.6.7-1.494.2.2 kernel, but it should also work with other kernel versions and distributions. Of course it's GPL'ed!

Thinkgeek has the hardware for this. Also a good explanation of what it does.
I use Romeo on my mac as a remote control; afaik it has similar features to sailing clicker, but with the added bonus of being GPL'd OSS Software :)
