Mouse Without Borders: One Keyboard, One Mouse, Two Computers

New and free from Microsoft is a program called Mouse without Borders.  If you two have computers on your network, sitting next to each other, why can't you control both with one keyboard and mouse?  Well, you always could with a KVM switch, but the hassle with that is that you have to switch between computers to have control.  You could not go seemlessly from one computer to the other, until now.  This program is extraordinary in it's simplicity.  When you get to the edge of your screen with your mouse, instead of stopping the mouse simply hops over to the second computer and is fully functional there.  No more switching the KVM switch, just move your mouse to the edge of the screen and it continues to the next screen, the second computer.  Watch the demo video from CNET to see it in action:
