Multiplicity makes it easy to set up primary and secondary computers. When you install it, it asks whether that
PC is going to be the primary or a secondary.
Once you define the primary, it allows you to define left and right secondary machines (custom interface for
those with more than 3 machines).
Multiplicity can search your network for machines with Multiplicity. It includes security to make sure other
people can't control your PC.
After you define your secondaries, it will guide you through setting up your firewall if you use one. Multiplicity
automatically adds rules for the Windows XP firewall. Other firewalls will have to be configured as instructed.
Enable clipboard sharing to copy images and text between machines as well as visual preferences.
Multiplicity has a wealth of configuration options, allowing you to completely configure how, when, and why you
switch machines.
