[Pay Per View] Pay pew view - Other Payment types

Hey guys,

I don't know if you can help me with this, but I need to implement other payment types apart from paypal on the pay per view plugin.

As Paypal requires to register for an account to make a payment, this highly affects the conversion rate for the pay wall, specially in the one off small purchases.

I've been looking at Payrexx and their API, and it seems like it could be a nice thing to integrate. Do you have any clues as to where I should start?

Thanks a lot in advance.
