Take a look at screen ( http://www.gnu.org/software/screen/screen.html ).  
That lets you create a session that can be attached and detached from
as many terminals as you want.  It has its own ANSI terminal emulator
on the backend and uses curses on the frontend, so you can attach any
terminal type to a screen session and the screen will send the
appropriate escape sequences.  Detach all the terminals, and the
session will run headless until you reattach to it.
