Do you have two or more computers on a network in your home or small office? Do you wish that you didn’t have to keep running back and forth when you need to do something on the other system(s)? Then Multipicity is for you.

Multiplicity is a new utility by the folks at StarDock. StarDock is the publisher of a great deal of software, including utilities and games. Most well-known is the program WindowBlinds, which has been around for a LONG time, in computer years.

Multiplicity is a program that lets you control more than one computer without having to leave your main system. When you run the program, you see nothing different UNTIL you move the mouse cursor beyond the edge of your main screen. At that point, you’re put in control of the other system. You have both mouse and keyboard support. It’s most effective when you have two or more computers close enough to each other so that you can see both screens at the same time. As you can tell, this can be a great tool. You can have your own system tied up with a major program (yes, it even works when running full-screen games!) and still be able to run other software or go online on the second system.

This new tool is a welcome alternative to expensive hardware called a KVM switch. Buying a KVM switch is just as effective, but can easily run into hundreds of dollars and involves a certain amount of plugging and running of wires. Multiplicity can easily handle three systems and goes for a mere $39.95 ($69.95 for the Pro version).

Support is very quickly available via the StarDock online forums. These forums are simply faster than most e-mail support services I’ve used, often returning answers in less than a couple of hours.
