Does anyone know if there are any jquery (or any other) modal dialog shopping cart /checkout mods available for osCmax?

I've searched around and found nothing, so I assume the answer is no, but perhaps I am missing something in my searches.

While we're on the topic, are there any similar options for product info pages? Where, rather than being taken to product_info.php, when a user clicks on the product, all of the info appears in a modal dialog box, with all of the same "add to cart" and image options available?

If not, can you rate the difficulty for a skilled programmer to create a modification like this? What it might cost?

Thanks in advance for any assistance.
