Would you happen to have any educational resources laying around about 
this so-called bone layering method? I'm trying to adapt Josh Sobel's 
face rigging method (http://www.joshrigs.com/) to blender, but ran into 
the problem of not being able to layer shapekeys onto meshes (a literal 
translation of the concepts, but I like what he does). However, this 
layered deform triggering sounds intriguing.
