Erk, well. I'm not sure you know too many ID'ers Doc_MAn. I certainly don't agree with many of the attitudes and positions that you represent as being typical of an ID'er.
Although, I guess to be more precise I fall into the 'fine-tuned universe' school of thought.
God may be perfect and infallible, but our understanding of God is far from perfect in my opinion. If there's conflict between our understanding of the bible and what we can scientifically measure then my suspicion is it's our interpretation of the bible that is flawed, or that the people who wrote down the words did not understand or could not properly articulate what God revealed to them.
As an example, the bible says God created the Universe in 6 days. My own belief is that the '6 days' of creation exist in a temporal space that is outside of our own time-space continuum. That is, God, being in (presumably) heaven took 6 days in heaven-time (lame term but trying to be clear) to layout his plan for/create the universe. The outworking of that plan created a new time-space continuum in which we live and the laws of physics etc are fixed and immutable for anyone inside of it. The outworking of God's process of creation in this universe need not have happened in the same order, or perceived duration, as the design process in God's timeline. Hence, the age of the universe and biological evolution of species is not particularly bothersome to me.
The closest analogy I can make is this. A movie has an internal timeline (within the plot of the movie) but the creation process of the movie exists in the timeline of the real world. A movie writer may write the screenplay in a couple of days and the movie might take months to film in the real world. However, the plot of a movie might only last 24 hours or it might cover hundreds of years. The ordering of scenes in the movie may be completely different than the order in which those scenes were conceived and filmed.
From a character in the movie's point of view, the movie-makers would have God-like powers since the director can quite easily rewind, change a scene, add a flying toroise, whatever.
The point is that to a believer in God, the notion is that God could not only create the universe, but he could create it so precisely that the eventual evolution of humanity was guaranteed if that is what God was aiming to do. (Heisenberg's uncertainty principle need not apply to God since he exists outside our plane of existence.)
I also do not hold with the notion that, since God put us here and gave us 'dominion' over the earth, we have the right to ra** and exploit the planet or the animals that live here. What I read in genesis is that the first task God set us was to be stewards of the planet. I'm a biologist. In my experience, material greed and the love of money play a far larger role in the extirpation of species than any religious view.
In any case, to answer the original question. No. ID is not /scientific/. I subscribe to Karl Popper's definition of things scientific as being an idea that can be tested, and that the results of these tests are reproducable. Since the required assumption of ID, that there is a God, cannot be tested the whole theory is not scientific.
Which is not to say it isn't true: just that it's not science. It's entriely a matter of faith IMO.
