It looks like an interesting concept, but if it truly is going to make it seamless to switch payment API providers they are going to have to store card details (assuming you don't want to store card details and you are currently storing card details on the gateway), since I don't think gateways let you dump the card details back out. It seems like the main value proposition is you can switch payment gateway providers (or use multiple ones for say canadian/us transactions) without having to move payment APIs. If I'm really trying to avoid having to switch APIs, what sort of gaurantees do I have that you guys will be around next month? One big concern for me is that it seems that if you fold I lose the ability to bill recurring customers unless I store CC data (something I'd rather avoid).
