Hi Guys, I really don't know enough about COLLADA to dive fully in on this topic, it's good to see it being thrashed out.
The only thing I can add to discussion is that we've had the issue of deciding whether an object is transparent or not in the OpenFlight plugin as OpenFlight itself doesn't say whether a geometry should be binned as transparent. This forces the OpenFlight plugin to take a best guess by looking at the vertex colours and imagery attached to textures to see if that data contains RGBA data with alpha values less than 1. To help with this there is an osg::Image::isImageTranslucent() method, perhaps something similar could be used in the COLLADA plugin.
