	Yeah, AFAIK there's no way to render this out directly.  You might want to 
mention that every 3D software package in the world renders layers this way, 
and many compositing packages like Nuke even have a handy button on the read 
node to deal with this invisibly...

	Never mind, that will just cause trouble.  I hate political stuff like this 
instigated by people that don't understand the tech...
