From what I understand when I read the blog, they're trying to demonstrate that you can use encryption/decryption on the GPU to create some form of DRM unique to your application. Their previous blog cites they are into researching some form of copy-protection systems.

As a once-upon-a-time iOS game dev, I can see it being used to handle In-App purchases where your game will only progress after you have purchased something and you get a key to decrypt the next level stuff. I can see it being used in that way. That's why I posted it here. It seemed interesting.
