Not that I know of.

There is that depthpeeling example Robert mentioned, but that does not work 
like expected. The way this example utilizes the depth test is very clumsy 
and unportable. You should use shadow samplers for that purpose.

I have something in the works here to implement depthpeeling in some way with 
our osg based application. I will, once this is ready, provide my test 
programs to Robert ....
