I agree that this is one of the tasks ahead for this model, but it
is going to be long term. One direction is to rule out alternative
physical models by showing that they don't seem to be able to support
life. Max Tegmark has a diagram at
http://www.sns.ias.edu/~max/toe.html
showing that small variations on our current physical laws would seem
to make life much more difficult.
Another approach would be to try to create simpler universes which would
still be able to support life. We could even do computer simulations to
try to show that life seems to be evolving. Failure to successfully
demonstrate realistic evolution would be evidence that you needed more
like the complexity of our own quantum laws.
