It sounds like you're talking about "PayPal Advanced" or "PayPal Pro Hosted". Our plugin currently supports "PayPal Payments Pro" which is direct credit card processing, not an iframe, and would require an SSL on the server.

Our 1.2.0 update that we're just about to release includes PayPal Advanced, so you could use that if that's what you've got setup. Unfortunately, we won't have Pro Hosted done for a little while longer.

Honestly, though, I prefer the full Payments Pro. The user experience is typically better and results in higher conversion rates.

The SSL is only around $75/year with your web host, and as long as you're not saving any credit card details on your server (which our plugin does not) then you would be PCI compliant.
