closest thing i'm aware of is VNC, which is loosely like
screen-for-your-xsession.  only problem is that it uses a virtual display
so you have an extra step between your x session and the console it
runs on (you will have a windows or x client that connects to your vnc session
no matter where you are, home or away, rather than just exporting your
home display (:0), it will live on :1 or whatever you ask for, >0, assuming
you have a physical :0).

so, it won't take a now-existing emacs session and make it available from
elsewhere;  you have to start emacs inside it (much like a program you'd
use inside screen).  

the cool thing is it's completely free, and works on everything from your
x session to your windows session to your palmpilot!  it's installed on the
cs machines (vncviewer/vncserver).
