iAd/HTML5 container

I have a webpage, which I would like to view in an overlay, in a Webkit browser. I assume we will have to re-create the webpage (it's very simple, HTML5) inside the iAd, or similar Javascript/HTML5 container, which is delivered as an overlay. So, I would be able to visit my webpage on iPhone (or similar Webkit enabled device), see my banner, select it, and view the contents in an overlay panel, and interact with it. My principal reason for choosing this method, is obscuring the source webpage. If I've chosen a method which is too difficult, or somehow stupid, I'm open to better ideas :) Thank you
