The Second Life Marketplace (for the virtual world Second Life) is something like this Photoshop Extension, enabling any SL user to sell their creations to other SL users.

Unity (the game engine and game editor) also has a marketplace, called the Unity Asset Store. It's integrated right into their editor / IDE.
Sounds like a cool idea. Best of luck with it!
Wonder if you can tie in with Adobe to verify authenticity of CS* product before allowing purchase.
Love it! Love it!
Marketplace as a Service? If that's what this is, and it sounds like it, that would be fantastic. For the last year or two we've thought that a marketplace would be a great potential fit for our app, but simply don't have the resources to build and maintain the infrastructure ourselves.
