Mac App Store

[thru]

Not sure if open a new thread for this question, let's start here specifically addressed to Jim that may have experience about it.

In the documentation about the App Store I see they refer to implementing the "app purchase api". Did you have problems or too much work with that? I ask in therms of having to call the api in Objective-C format or other things that may be complex for a Qt developer that didn't scratch the surface of native Mac developement.

Thanks!
Juan

Edit: Reading deeper I see that the app purchase api apparently refers to the cases of selling goods rather than software apps so maybe my question doesn't apply, anyway, in a more broad meaning, did you have to dig into non-Qt technologies to make your app compatible with the appstore?
