When I read Behe, what I got out of it was that irreducible complexity better boils down to "We can't figure it out with existing theories, we need to study more/a new theory/whatever - we need more, and improtantly, better answers." Creationists using it as an signpost pointing their way are silly. Conversely, scientist frightened by discussion of the idea (which they are too many), are doing their chosen craft an injustice.
For the love of God, what am I doing here? I know better to even post on a creation/evolution thread. So what do I go and do? Try my best to piss off both sides. Not smart, to say the least....
