geolocation as trigger?

Hi everyone,

I've hunted around, but I don't think anyone's asked this before, so...

I'm imagining a story that'd be played on a mobile device. Some decisions, branches would go as per normal; others would require the player to be in a physical location to reveal new options (or indeed, new passages). For this to work, I'm imagining a javascript chunk in a passage that would call html5 geolocation api?

Would that work? Could that work?
