Yeah, pretty much. It seems like the owner of the asset should enter explicitly into a relationship with the App Store otherwise they may not be happy that all these third parties can add extra fees to their assets. I guess that's what you mean by creating sale restrictions?

Also, I think there will be legitimate cases where someone wants to sell something through a marketplace but doesn't know how and doesn't care. In the app store example, let's say a developer wants to sell an app through Web Store Foo but the developer doesn't want to do all the asset signing / crypto, etc. Balanced fills this need nicely: all you have to do is securely enter your bank account details, list your goods through the marketplace, and you get paid. It should be that easy. Maybe offering third party asset management tools is the way to solve this.
