Amazon Simple Pay support

I was just getting ready to upgrade to Pro Sites and see that you ditched Amazon as a payment gateway. I was really excited to be able to use Amazon instead of Paypal. The Paypal thing is the only issue keeping me from being able to use the Pro Sites plugin to manage my site. The number of issues people, and myself, have had with Paypal holding money hostage terrifies me. Is there any hope of bringing Amazon or Google Checkout or Authorize.net online as a gateway? Paypal is absolutely the easiest and WORST alternative ever. The plugin is awesome though.
