Guys, there is another way, but requires rendering on the clients (and so, they can't be really "thin").
I haven't tried that, but Xming is an X11 server for Windows that apparently supports OpenGL (http://www.straightrunning.com/XmingNotes/#head-141). You can run stellarium remotely, but the rendering will happen on the clients. I don't know if it fits your usecase. I can't really test it now, since I don't have any spare windows machine around...
