Wait wait, so if I know the "secret" SMS format I can text someone's phone and get their coordinates back?

No, the SMS is initiated by the device upon calling emergency, not requested by the emergency service. The standard is called AML.
The format is not secret either, it's just binary encoded.
Ahh OK, well that just sounds reasonable.
