Duplicate HMD display on primary monitor, with eyetracking info

[farshizzo]

Have a look at the <node>.renderOnlyToWindows() command. It allows you to control which sub-windows a node will render to. There is no need to clone/duplicate nodes and scenes. Just add everything to the same default scene and use this command to customize the rendering for certain windows.

Let me know if this doesn't address your specific problem.
