Tusko,
You've just got me thinking, and I may be going off at a tangent, but the assumptions underlying ID are quite interesting. ID seems to assume that God would not build a creation that could appear to have arisen by chance. For instance, if he was to make genuinely irreducably complex structures (assuming that's possible), then that's a blatant neon sign saying God was here.
The problem here, as you acknowledge, is finding an IC structure that absolutely, definately, could not have arisen by the addition & subtraction of sub-structures. Since we cannot know that any given IC structure is not
potentially unevolveable, it's moot.
