Good ideas.  There might be other options to extend emergency use of

1. base station switches to sms only mode during emergencies if that will
significantly extend backup power time

2. each carrier accepts sms traffic for any other carriers' customers during
an emergency (we see something like this for emergency 000 calls now)
