TOPIC: No PayPal PRO?

As a long-time and happy user of DT Register, I did not hesitate to purchace DT Donate. It is for the same site using DT Reg, but for a donation to an affiliated charity. I was surprised to find that DT Donate does not support PayPal Pro. We'd like to use the same processor as the registration page and be able to process payment without redirecting the user to paypal.com. Is this on the road map for future release? How hard would this be if we wanted to sponsor this addition given that it has already been done in DT Reg?
