i think if it was just a toggle, it would have been done.  let me see if i can find his post about it.  this is what he said, "I didn't have the time to follow Blender's Python update because of my work on Reality. Maybe in the future..."  and just from poking around, yeah, they seem to be changing how things work pretty constantly and fast.    like basic structure.   i don't think they keep the Blender API even close to stable, from what i've read in random comments here and there.  i'm sure updating is possible, just non-trivial.
