synergy
"Share mouse, keyboard and clipboard over the network" - you only need one mouse + keyboard to control several desktops w/ displays.
Synergy is a very good alternative to x2x/x2vnc. It features Windows, Linux and MacOS clients and does a bit more than x2x or vnc. It can not only share your clipboard to all machines attached, but also disable all screensavers/locked screens at once.
