How-to: Share your keyboard and mouse in realtime with Synergy - Engadget - www.engadget.com: "Synergy is an open source and free software project that allows one to share a keyboard and mouse across multiple monitors on separate computers and even between different operating systems. You may be a prime candidate for Synergy's superbum synergy if you code multi-platform software, use more than one computer at home such as a laptop and a tower, or if your computers have different functions (media server, net machine, etc.). Personally we do all of the above and were in dire need of a swift way to dispose of our old keyboards and mice to make way for all sorts of fun new usb gadgetry."
