Today I achieved the following setup by dividing my openni2_launch files into two separate launchers beeing executed on two different machines: one for processing (nodelet_managing) running at a powerful server and one for streaming the [amazon &title=Xtion&text=Asus Xtion]-Image data from the [amazon &title=CubieTruck&text=CubieTruck] to the /camera -topic namespace. After that I could visualize, what my laptop wasn’t able to do before: a 3D DepthCloud with RGB-Data coloring in rviz. It has a native resolution of 640*480 and looks like that:

I can’t say how efficient the load is balanced right now – because I am currently still optimizing.
