Well, you've mentioned it enough times, so I finally signed up for a developer account. Very interesting solution. It took me a while to realize that it doesn't manage your products at all. It literally just provides the checkout process, so I guess any form I can build, it can process.
Integrates with a lot more than Wordpress too.
