Sorry I don't understand what you mean. If you simply put (at the top 
level) parts like this:

SCENE
|-CLIP
     |-Childs
|-NON_CLIP		
     |-Childs

the childs in this example can have arbitary transformations...
If you cannot place your nodes like this, you can take a look at the 
ClipNode-implementation and maybe inherit and change the parts that 
control the clipping state to set it effectively per child somehow.

The other option is to simply use a shader that implements the clipping 
and to switch it on/off via uniform.

Cheers
Sebastian
