Synchrony is a modified version of Synergy. The possibility of clipboard data transfer has been removed, and the keyboard and mouse input is now routed through a KM switch, which switches automatically via RS232 communication when the mouse cursor reaches an appropriate edge.
The first incarnation of synergy was CosmoSynergy, created by Richard Lee and Adam Feder then at Cosmo Software, Inc., a subsidiary of SGI (nee Silicon Graphics, Inc.), at the end of 1996. They wrote it, and Chris Schoeneman contributed, to solve a problem: most of the engineers in Cosmo Software had both an Irix and a Windows box on their desks and switchboxes were expensive and annoying. CosmoSynergy was a great success but Cosmo Software declined to productize it and the company was later closed.
Synergy is a from-scratch reimplementation of CosmoSynergy. It provides most of the features of the original and adds a few improvements.
