Here's an idea.. First, apply a ClusterCullingCallback to each icon, with the normal vector being the up-vector at the icon's location. This is prevent icons from rendering behind the Earth .
Render the Earth normally, and then also to the stencil buffer. Increase the render bin # of the icons so it's higher than that of the Earth. Then, render the icons with an osg::Stencil attribute. Set it to pass on either z-pass OR stencil-pass. Finally, render everything else as usual (planes, etc). Maybe?
