My experience is that theistic evolutionists such as Ken Miller see god's handiwork in extremely subtle ways. Miller, for example, places god in the realm of quantum mechanics. Since QM is an exercise in probability, he has god's actions happening on probabilistic levels, tipping the scales in certain directions rather than dramatic, Spielbergian zap-poofing.
My impression is that Ken Miller keeps his theism and evolution entirely separate. He denies being a theistic evolutionist in that he finds evolution to be too haphazard to have been guided by God.
That said, I think the term "theistic evolutionist",
in broad definition, might incorporate everyone from theists who are evoluionists (such as Miller) to those that think God micromanaged evolutions path.
Intelligent design has generally been so vaguely defined that everyone from young Earth creationists to theistic evolutionists can incorporate it. I would presume that anyone who believes in a creator God would think that he/she/it had some intelligence involved in the creation.
I now repeat my assertion that Michael Behe has the most solid ID position that I know of. I would definitely consider Behe to be a theistic evolutionist. He is a mainstream evolutionist trying to document God's fingers in certain details. Not that his efforts have at all held up.
