I found this wonderful tool to share your mouse and keyboard over multiple machines. I use this when I have two computer (like my two laptops) so I never have to take my hands off the one keyboard/mouse. When I am in the main room, this tool allows me to control the house computer without VNC since I can see the monitor fine, but am too far to use the mouse and keyboard. It is very easy to setup (though some settings do not make themselves obvious).
I have not played with the cross platform options, but it sounds great if you have a serious setup at home.
This is a great open source app. Simple, clean, and just works. Well done Synergy.
