Desktop Rover allows you to control multiple computers (and Pocket PCs) with one computer's keyboard and mouse. A graphical group configuration UI makes it very simple to create and modify your virtual desktop. You can copy most clipboard data (including files and folders) from one computer and paste it on any or all of the other computers in the group. Multi-head systems are supported and remote computers can be controlled before a user is logged in.
Version 4.1 adds setting to hide icon on Pocket PC, setting to bring mouse home (or not) when screen saver becomes active.
