It is just active desktop 3.0, so, it has its uses. I wouldn't go with that route because using IE as middle layer is putting yourself at mercy of its hardware support and versioning changes, that often is unstable at beta stage, and I don't know what terrible things have not been fixed at final release. When something goes bad, you have to consider your compatibility with current version of IE, which increases complexity. It sounds good for wen guys. But good for long run.
