I share your suspicion, but I haven't gotten that far (i.e. asking them what they think). Even if emergency responders don't want it, I still think it's a good idea.  Just have the app call friends & neighbors instead. EDIT: Just ran across this randomly. 911 will soon accept texts, photos, video

As for twilio, the api does use XML, but all arduino needs to do is ping an web address with some identifier on the end of it to set off the chain of events that is handled by the webserver.  Unless I'm missing something, the load on Arduino, for this purpose anyway, is minimal.

pseudo code (admittedly bad pseudo code)...

arduino activated ---> ping http://mysite.com/alert.php?id=secret_code

-----------------
alert.php
-----------------
if($_GET['id'] == $secret_code){

     $twilio->call($audio, $numbers_to_call)
     $twilio->sms($text, $numbers_to_text)

}

The audio file could be placed just about anywhere.  Amazon S3 is my initial thought, because it's uber inexpensive and more reliable than many other hosts out there.

Hope this helps.

I suggested Twilio because it's easy to implement as a way to call the authorities and call/sms family, friends, neighbors in the event that the button needs to be pushed.

Lately there have been a series of burglaries in my neck of the woods that got me thinking...

Wouldn't it be nice to have a "panic button" of sorts that we could place by the bed that alerted the authorities if there was an intruder in our house while we were at home (unfortunately, the recent events were just this).

Arduino and Twilio both instantly came to mind.  I know nothing about microcontrollers or programming them and don't have time to learn at the moment, but thought I'd toss the idea out there to see if anyone would like to tackle it.

Here's what I'm thinking.

1.) user panics and presses a button on a key-fob. Something like http://amzn.to/n3X2Wb OR http://t.co/FqDh2BB
2.) the receiver is connected to the arduino with an ethernet stack
3.) the arduino uses twilio to make phone calls or text messages (one or many) with a pre-determined message(s) that alerts the authorities and or neighbors/family members.

As I said, I know nothing about microcontrollers or arduino except that it's cool.  The twilio portion of this code is incredibly simple though.

I've spent some time thinking about this, so I'm happy to answer any questions.  Hope someone takes this and runs with it!
