Constant Contact Integration?

I've always used the acymailing integration in the registration step of the checkout flow (little checkbox for opting into emails). However, we typically use constant contact for our email correspondence, and it's a pain to continuously export from acymailing and import into constant contact.

Are there any plans to extend this to other popular mailing platforms, such as Constant Contact?
