Ever have to use a KVM to jump between systems? My buddy Anthony showed me years ago of a nice small software that links one set of keyboard and mice between multiple computers. It works to link Windows, Linux, and Mac OS keyboard and mouse control from one host system and control other client systems. I've used it to link Windows 7 to ArchLinux and Windows 7 to Windows 2008 R2. You then can have multiple monitors and OS running and not have to switch between multiple keyboards and mice to control the systems. I'd recommend using the Beta version as it's a bit easier to configure. It was a hoot to use the first time, so I thought I'd share.
