Ratpoison, nor any window manager can do this. X clients connect directly to the server (i.e. your screen). If the screen detaches, all clients loose their connection thus are terminated.
The (only) solution is to use a special X server. vnc is one such server, that offers a remotely controllable desktop on one side (for your screen) and an X server on the other side. Thus if your screen detaches, the X server with all its X clients continues to run. See tightvnc (http://www.tightvnc.com/).
