Thanks for the reply, Corey. I have looked into WorldPay and Paypal and despite a good deal of reading on their websites, can't determine for sure whether either of them would work in this situation (and for now they haven't answered my emailed questions - though that may be the holidays ;)

For example, I can't figure out if Paypal offers a complete API which enables them to take care of the complete transaction, while being entirely transparent to the user (as is possible with authorize.net) It sure looks like their "Website Payments Pro" solution offers this, but I'm not totally sure from their presentation.

Worldpay doesn't seem to offer such a solution.

I just learned of Google Checkout - but they say for now that it is only available to US or UK merchants, so that rules out that solution.
