QSynergy is a comprehensive and easy to use graphical front end for
Synergy.  Synergy lets a user control more than one computer with
a single mouse and keyboard (and has lots and lots of extra features
on top of that).  Synergy itself only comes with a GUI for MS
Windows.  QSynergy was written to fill the gap for users on Mac and
Unix platforms.  Of course, it runs on MS Windows as well.
