Authorize.net Direct Post Method (DPM) API, no SSL and PCI Compliant

I would like to place a feature request for Authorize.net Direct Post Method (DPM) API integration. I know that Marketpress only works with Authorize.net's (AIM) Advanced Integration Method, but seems like it'd be more useful to integrate DPM, and I know its new so maybe it wasn't available when Marketpress was initially being developed, etc.

BTW - here is a helpful overview for devs interested in Authorize.net comparison of payment methods: https://developer.authorize.net/api/compare/ The nice thing about DPM is it requires no SSL and is PCI compliant.

Any other members interested in seeing this feature a priority?
