Glad that card works well for you.

There's not much to it.

1). I don't know which desktop environment you're using so you much find
arrange for the "-nolisten tcp" not to be added to the XServer when it
is started.
  a). For XDM edit /etc/X11/Xservers - it has been added to the command
      that runs the Xserver.

  b). For GDM take a look at /etc/gdm/gdm.conf and make sure that
      DisallowTCP is set to false.

2). On the NVidia system arrange that the following command is run as
part of the X11 start up procedure (like adding it to "~/.xsession").
   xhost +
This configures the X11 server to allow any X11 app to put its display
upon that server.

3). To run a app and have it send its display to a given display 
there are two ways.
  a). Use the --display <display> option
  b). Set the environmental variable DISPLAY and set it to 
      <display>.
For details of the settings of <display> see
  man 7x X
and look at section "DISPLAY NAME"

4). To use the mouse and keyboard on a remote system to control the
mouse and keyboard of the remote system see x2x(1) (apt-get install x2x).
