Synergy is a cross-platform keyboard-mouse switch. It’s also one of the most well-named pieces of software out there. Here’s why: I had a laptop running XP with a nice usb keyboard and mouse plugged into it. To the right of that, I had a laptop running Linux. Both computers are on a wireless network. Using synergy I can slide the mouse off of the right edge of the screen and onto the Linux laptop’s XWindows screen with no lag. In the process it transfers keyboard control over to the other system too. You can even cut and paste between systems. This is a great solution for using your desktop keyboard with your wireless laptop or if your laptop is sitting in the living room you could easily use its mouse and keyboard to control your home theater pc. Set up is simple, scales easily, and works with OSX, too.
