IMHO, the Discovery Institute threw a prime rib roast into the arena of hungry theologians and scientists. It seemed as if the effort stopped with the hypothesis and they sat back waiting for investigators to come up with the experiments to evidence or falsify the hypothesis.
Personally, I believe they are excellent strategists and it was intentional to separate the politics and legal aspects so they could play out separately that they always knew the mathematicians and the physicists would vindicate the hypothesis.
I have no other explanation for the cautious, superb wording of the hypothesis which says:
The intelligent cause keeps it from being theology and opens the door to phenomenons such as emergent properties and fractals.
The universe and life changes the focus from strictly biology to cosmology, physics and math (which is the key).
The undirected process such as natural selection reveals the target: randomness. In that regard, I can think of two unequivocal statements which will make the point without any help at all from the Discovery Institute:
Order cannot rise out of chaos in an unguided physical system. Chaotic systems, by definition, must be bounded, be sensitive to initial conditions, be transitive and have dense periodic orbits. Order requires a guide.
That subtle change of expression from random mutations to variations leaves the door open to autonomous biological self-organizing complexity and thereby the vindication of the hypothesis even if every single one of the investigators deplored the entire "intelligent design movement".
I have absolutely no idea of what you mean by an "unguided physical system", or what you might mean by a "guided" one. How does this not flatly contradict your earlier paean to the concept of "emergent properties"? Emergence is all about order (or higher levels of organization) arising spontaneously, i.e. without specific guidance, in complex systems.
