Ok this looks very interesting. I have multiple e-commerce stores (I love building them, especially drop ship stores) . . . That being said, I use Shopify a lot, how will this integrate with Shopify?  I use Coinbase and Bitpay for payments through Shopify, and really I just don't care for either.

I would be willing to signup and try, but it has to integrate with Shopify because I won't change my whole site, just to test your payment system. =)
