Great Idea, but just know that it has been done.
Although, something that would be new and cool would be the ability to be able to view animated textures on-the-fly (like you're really in the zone) in the "previewer", and stuff like that. Otherwise, it'd only be an extra app to load to do the one thing that openzone already does. Hope this helps.
