synergy: sharing the keyboard and mouse

There are many occasions at which a user needs to use two computers at the same time, even with two different operating systems, all in the same desktop. One of the most annoying things that might happen is that you will need to use a different set of keyboard and mouse for each computer with the resulting waste of space on your table.

One of the first solutions that firstly came to mind was to use only one set of keyboard and mouse to access the other computer through some kind of terminal software such as VNC, ssh, FreeNX,… but, sometimes we would prefer to really use the other computer, providing us with access to two real screens (very comfortable), for graphical design tasks, games, closer feeling to the user interface, etc. This is the case we are going to talk about.
