Hi. I found this site and it seems to be what I was looking for. I am under the assumption, and hopefully someone can confirm or deny, that Zen may be used as a cart with the Google checkout.

I am in the process of building a web site using asp.net but am having problems as far as the checkout and payment screens. I have built simple sites in the past but nothing that incorporated payments and checkouts.

Simply put how does Zen work and is it fairly easy to integrate into a web site? How exactly does google checkout work (not familiar with it and hopefully someone can answer)? Does Google checkout use methods for CC transactions? (perhaps I will ask these over at google, but would appreciate it if someone knew). Finally, does google checkout return an XML schema or flag that confirms payment, so that I can reduce my inventory within the database?

Lots of questions. If I have missed the obvious please feel free to chip in. Thanks again!
