Broke My Controller Writes:
You're on Xbox LIVE and a friend asks you to join in for some Modern Warfare multiplayer. Unfortunately, you never purchased the new map pack DLC. A recently published patent application by Microsoft shows off an automated system for purchasing DLC through a prompt that comes up as you accept an invite that requires content you don't have.
According to the patent, you will remain partied up, and rather than having to go to the Xbox LIVE Marketplace, you will be given the option to purchase and install the content automatically.
