I've done this kind of thing just hooking into the asset pipeline. (In Rails 3.2) ActionView::AssetPaths#compute_public_path is called to generate public paths from any asset path (JS, CSS, images, etc.) so by overriding it and rendering a view, you can capture all the assets referred to by the view (unless you have non-pipeline assets, e.g. in public/).
