To put a less formal flair on it than Wounded King and Omnivorous, what you're requesting goes something like this: "Hey, evolutionists, here's an irreducibly complex system, how do you explain this one? Oh, well, okay, how about this one? Oh, well how about this one? Oh, well how about this one?"
It takes a lot of time and effort to tease out the possible evolutionary histories of microbiological processes and structures, and in many cases there simply isn't sufficient information or evidence to do so. With no compelling evidence in favor of ID, and combined with the obvious origin of ID as a movement within evangelical Christianity motivated by a rejection of evolution (despite all the denials), only scientists who take the threat to science education seriously will be motivated to put time and energy into developing scientific answers to the questions posed by IDists like Behe.
A similar analogy would be theories about aliens on other planets. Someone says there are aliens living on the moon. We go there, no aliens. So he says there are aliens living on Mars. We go there, no aliens. So he says there are aliens living on a planet orbiting Alpha Centauri. We go there at great expense, no aliens.
At what point does this silly process stop? To anyone familiar with science, disproving aliens and disproving claims of IR is patently ridiculous right at the outset, and to explore even the first claim makes no sense, because there's simply no evidence supporting the original claim, just a desire by a significant religious community that it be so.
