The response was that ID was under no obligation to satisfy the expectations of the scientific community for what a theory should look like.
I see this as just an admission that ID is not science. When we say the word theory, we mean implicitly scientific theory.
In short, there is no theory and Meyer admits that.
This was one of the main points in the Dover trial from a few years back, when Behe was trying to provide his advocacy for the ID side of the fence. In the end, he had to admit that his notion of science did not meet the standard definition and when pressed, also had to admit that if one used his definition, then concepts like Pyramid Power, Astrology and Magic Crystals would also have to be acknowledged as being 'science'.
Science is science and the scientific method has already been defined. If one has a concept that cannot reconcile against these established notions, then it is simply not science. No matter how they want to spin it.
