The ludwig shape keys into the GE?

I just rigged a human character using the ludwig rig I found on the Essential Blender CD, but I can’t figure out how to get her shapekeys to work in the Game Engine. I got the rig working and her jaw and eyes moving, but the ludwig uses a rig that controls her shapekeys to make her lips smile, frown, and pucker. I tried using the shape key action, but it doesn’t seem to work. Is there a way to use the ludwig face control rig in the GE, or will I have manually have to slide the shapekey sliders to make her smile in the GE?
