Lets put it this way. There are many forms of ID in part because different religionists have different needs. Some can accept common descent, such as I think Behe et al. Others prefer other things. The whole ID thing is a big mess precisely because there is no scientific work going on. As a hypothesis, the idea that life on earth is designed etc cannot be proven to be completely and utterly wrong, but since there is no cinvincing evidence for it and theres plenty fo evolution, then it is not correct. If you go to Pandasthumb.org you will find a variety of ID'ists pontificating about what htey think, some of them claim not to even be Christians. We, as commentatotrs on teh problem will have to define ID'ers by what they say, and since there is no unifying principle of ID, we will egt different answers from different people. All we can do is maul each different idea as it presents itself, as has been done by evoloutionary biologists already.
