Is Intelligent Design Scientific?

Intelligent Design is often dismissed as unscientific because it violates various criteria used to define "science." One of the restrictions imposed upon science by some philosophers is "methodological naturalism." This rules out any hypothesis that invokes a non-materialistic cause such as an intelligent designer.

I reject that limitation on science as a way of knowing. Are there any other reasonable definitions of "science" that can be used to exclude Intelligent Design while still including other hypotheses that we'd like to keep?

Here's Stephen Myer arguing that the answer is "no." Is this a good argument? Note that I'm not asking whether you agree with intelligent design. I'm simply asking whether there's a good argument for dismissing it as nonscientific and, therefore. should never be discussed in a science class. If you think the answer is "yes" then please give a definition of "science" that excludes Intelligent Design but includes speculations on the origin of life, string theory, and whether Bigfoot exists.
