I deal with the PayPal team regularly, and I'm sure they'd be interested in your success. Are you in/near Paris? We (Magento) have an event there in early February. Happy to meet up then or sometime / somewhere.
About the Paypal. For me personally that is a reason we are forking. Last year the company that develops the Paypal module for PrestaShop got into an affiliate fee dispute with Paypal. They released an "update" of the Paypal module that basically made every UK shop's module disappear on the checkout for customer. People in the UK had a shit fit. I mean who releases an updated module that is meant to punish users to prove a point to Paypal? Totally unacceptable.
