Userful Live CD is a unique multi-station / multi-headed Linux live CD that lets one computer function as two. Booting from this CD temporarily transforms your dual-monitor PC or laptop (with an extra USB keyboard and mouse) into a "dual-station" PC, supporting two simultaneous independent users, each with their own screen and keyboard. A single keystroke links your keyboards and monitors. This live CD also includes Userful's Desktop Multiplier and DiscoverStation.
