Multiplicity is a program for Windows XP/2000 that allows users to multiply their computing power by connecting multiple computers in an office together as a single computing platform. It does this by establishing a high-speed network connection between each machine. A single “master” computer has a keyboard and mouse attached to it. The other computers in the room continue to have monitors connected to them. The user then assigns where each monitor is positioned in a fashion similar to setting up a multi-monitor setup. The user can then control the computer based on which computer’s monitor the mouse cursor is. Multiplicity sets up a universal clipboard between the machines (the Pro version even allows users to copy and paste files and folders between machines), allowing them to work together seamlessly.

Multiplicity is useful to a wide range of users including IT departments, testing centers, power users, gamers, and more. What makes Multiplicity special is how easy it is to set up and how reliable it is to work with. Version 1.02 includes enhanced machine detection allowing users who have Multiplicity installed on their machines to quickly connect them together. It also includes new options for hiding the system tray icon and a few other usability tweaks.
