Simultaneous control of multiple Xwin applications

Multiple copies of a graphics application, maybe 10 of a package called 
Enliten from CEI for example, are running in a single XWindows manager (say 
GNOME). One copy has the focus. I want to control the image in that focus 
window (3D view rotations, zooms, translations) and have similar images in 
all the other copies of the application follow that same control stream. 
Basically I want the stream of mouse commands arriving at the focus window 
to be recognized and processed by the other windows even though they are 
not the focus. Eventually similar functions with keyboard input will be of 
interest.

Is there something that can already do this? Or do I need to develop from 
scratch? I see x2x (for multiple Xwindows displays), gpm (for dual 
console/xwindow sharing of mouse) and multi-open (kernel option to maybe 
send device control to multiple consumers), but nothing appears to do what 
I need directly.

Recommendations on options and/or places to look would be greatly 
appreciated. Also, please let me know if I should be checking on a 
different forum.
