PS - It's not "cluttered" at all, as it's simply an underline (or other unobtrusive indicator, such as small "Help" info (e.g., "i for info" icons) on or adjacent to existing UI labeling denoting help popups available. That's the entire point (to not clutter the interface with always-displayed help text, but displaying it only when the user wants to see it, which is facilitated by a brief delay in displaying the mousover popup, to avoid inadvertent display unless the user hovers over the desired label for a certain amount of time). The other point is that it intrinsically ties help "articles" directly to the relevant UI elements). Our users have responded quite favorably to this strategy, and the IPS ACP could really benefit from this, since so many features are not at all "intuitive", in terms of how they are intended to work, or what the correct setup options are for any given scenario. Microsoft and others use this approach extensively, so it's hardly controversial or "ground-breaking". It obviously requires a sound balance between brevity (of a popup) and the verbosity of a full-on external Help article.
