The default is to have '-nolisten tcp' in /usr/X11R6/lib/X11/xinit/xserverrc (I think this is where it is - I changed it long ago). If you use a display manager then that probably is also set to use '-nolisten tcp' by default - I think that is done in /etc/X11/xdm/Xservers. Remove the '-nolisten tcp' from these locations, use xhost to allow connections from the other machines, and you should be fine.
