Hmm, ok. What I'm searching for is a solution that would both fit for me but as well for the OpenSG community in general. For me both solutions would be ok, but in my opinion creating a 'FBOWindow' class may require less programming work as the current FBOViewport implementation (which is huge) can be left untouched. Regarding cleanness of the approach I would rely on your knowledge of the overall OpenSG approach. So what do think about the direction to go?
