So, my friend at work, Mike, showed me Synergy today. PRETTY FREAKING COOL! It is not ready for prime time yet, as the UI is a little clunky, but the functionality works and allows me to just use one keyboard and mouse to control the laptop and computer at my desk. It is different then the hardware needed like a Belkin, and it doesn't allow you to use the same monitor for multiple computers, but it does allow you to make all monitors aware of each other, so that your mouse can jump from screen to screen to screen, regardless of your operating system.

And best of all... it is free!
