I think that's exactly what the XRender extension is supposed to do. It 
works fairly well, but it does apparently still work with a snapshot to 
create transparency. I don't know enough about the X11 protocol to say 
anything definitive, but I think, part of the problem is that hidden 
parts of the desktop are just not transmitted for a redraw which would 
be necessary for true transparency to work.

Another problem that's rather serious is the question "what for". IMHO, 
that's the real problem hampering the development of such gimmicks.
