Remember SynergyKM, the GUI tool for installing and configuring the open source keyboard/mouse sharing application Synergy? Another pair of developers have released QuickSynergy, an another GUI-based alternative for implementing Synergy.
QuickSynergy doesn't actually require the installation of Synergy to work as the binaries are within the QuickSynergy application. All you have to do is download and run QuickSynergy and then configure it via the application. Very nicely done.
