conspy - Remote control of Linux virtual consoles
Conspy allows a (possibly remote) user to see what is displayed on a Linux virtual console, and send keystrokes to it. It works with Linux and FreeBSD, as far as I know. It is rather like VNC, but where VNC takes control of a GUI conspy takes control of a text mode virtual console. Unlike VNC, conspy does not require a server to be installed prior to being used.
