Hello Brad,
My other problem with IDE's, such as eclipse, is that it's such an all or nothing investment. You can't really just use part of it. You must buy in to it's editor, it's interface with your SCM, it's scriptures of indentation style, etc. Trying to deviate from any of it is such a large pain that it's just not worth it -- more so as the team working on a project gets larger.
For VS, you might have a point. However for D, I use Descent and I haven't found any of those to be a problem. Getting people to agree on how to set it up I expect would be a bigger problem.
