Petition to Apple to Create/Improve APIs to Allow Augmented Reality Apps on the iPhone

Apropos my recent discovery of camera heading in iPhone metadata comes word of a petition for Apple to create functions that would allow Augmented Reality development on the iPhone:

Augmented Reality are applications that combine computer-generated imagery (or text) with imagery generated from a camera. Examples include applications that show historic photographs from your current vantage point, identify significant features in the landscape (buildings, mountains, constellations), and games.
