Userful Live CD is a unique multiseat 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-seat" PC, supporting two independent users at the same time, each with their own monitor, keyboard, and mouse. A single keystroke links your keyboards and monitors. The live CD also includes Userful Multiplier and Userful Desktop.
