An OAM widget creates an iframe, so you would need to dynamically adjust the iframe's src code to be http://example.com/hypeDocument.html
into something like http://example.com/hypeDocument.html#sceneName
if you're using the Scene URL JS code you linked. Since this reloads the JavaScript, there will be a brief flash as content is loaded, so it may not be the best solution for a seamless linking experience.
