Multiplicity is a program that enables a user to control multiple local personal computers as a single computing platform. It works in a similar manner to a single machine with multiple monitors. Except in this case, each monitor is connected to its own computer. The primary computer has a keyboard and mouse connected to it while the client computers do not. When the user moves their mouse cursor onto a different monitor, they are controlling the computer that the monitor is connected to. The result is that a user who has more than one computer in their office can put them together and control them all from a single keyboard and mouse. Multiplicity, ultimately, is designed primarily for users who want to increase their productivity. If you?ve ever emailed yourself a file or image or document from one computer to another, despite both being in the same room, you need Multiplicity. If you?re sifting through keyboards and mice in your lab or office trying to control multiple computers, you need Multiplicity. If you?re a gamer who wants to be able to play their game (such as a massively multiplayer game) while still being able to do ?real stuff? you need Multiplicity. If you have an ?older? PC lying around collecting dust that you wish you could still do something with, you need Multiplicity. If you?ve just gotten a new machine and find it tedious migrating your files, data, settings, and work from the old machine to the new machine, you need Multiplicity. If you?ve ever wished you could toss another processor into your computer or add a bunch more memory so you could load more things to work on more projects during the day, you need Multiplicity. Version 1.1 adds Windows Vista support, support for monitor placement above and below the primary machine, numerous bug fixes, and more.
