It would be a damn useful feature for an alarm system. Someone breaks in triggers an alarm and boom 911 gets dialed.

No, it would not be damn useful- if your alarm system dialled 911 to my center, you'd be well on your way to not having a phone line. Automatic diallers should be set to a non-emergency 10-digit number. Alarms are well over 99% false calls. That's why most places will start charging you for a police response after your 3rd false alarm. 911 in the U.S. is reserved for emergency calls only- there is no other use for that string of numbers.
