Use One Keyboard and Mouse For All PC in Network

Hey!!
Some time I need this feature badly. I cant change my location every time for just use mouse and keyboard of other PC. This is different from KVM. A familiar phenomenon for the geek with a laptop for on the go and a desktop computer at home or at work. Instead of splitting your computing power over several displays, you’re putting several disjunction systems in parallel. 
ShareMouse lets you share your mouse and keyboard with multiple networked computers.
Just move the mouse pointer to the computer you wish to control. When you reach the border of any monitor, the mouse magically jumps to the neighboring monitor and you can control that computer.

 

ShareMouse (Mac + Windows)

ShareMouse does exactly what you would expect from a KVM switch, and more. After installing the application on two or more computers, ShareMouse will automatically spot other computers running ShareMouse on the same network and connect with them. ShareMouse is available for Mac OS X and Windows computers, and will work in both directions.
With ShareMouse, you can use one keyboard and one mouse to control all devices on your desk, or you can use the computer you’re currently working on to pull up information on any of the other computers.
