PayPal Advanced plug in Before Checkout

Has anyone figured out how to run the PayPal iframe on the payment info page?  

Quanntex makes a nice plug in, but runs after the order is complete.  The natural way customers use the cart is by providing payment info, getting an auth, then confirming the order and payment auth.

I looked at deconstructing the Quanntex plug in, but my skills are just not good enough.

Any suggestions or comments are greatly appreciated.

I have experience with PayPal Express In-Context Payment, it works like you described - preauth before order is made. :)

Thanks for the quick response.  Have you looked at creating a plug in for PayPal Payments Advanced?
