So along those lines, you could make it work with existing attributes. A blank `ic-src` could check for an `href` attribute on an element. An `ic-post-to` and friends could look for a parent form and grab the `action` attribute.

All in all, I think it's a neat idea. Since you give Rails examples, it might be nice to include some Rails helpers as separate project/gem that make it so you don't need to write so much boiler plate in your views.
