Ok, I have to share this new program that I just found via discuss.joelonsoftware.com: http://www.keyboard-and-mouse-sharing.com/ "ShareMouse" allows you to control any of your PCs with the mouse & keyboard of any other computer. If you have multiple computers on your desk, this is the software you want. Works better than Synergy. ZERO configuration. And unlike Multiplicity, it also works on the Mac as well as Windows.
