Mailing lists are useful for a wide variety of things, but VT-type
emergencies are not among them.
IIRC, just a day or two after that event, the CIO of VT came to this
very list to ask for assistance in setting up Mailman for future
cases like this, to send out emergency notices to everyone on campus.
My understanding is that he went away very disheartened when he was
1. The inherently unreliable nature of e-mail and how long it
can take to get delivered under "normal" circumstances
2. The more time-sensitive the subject, the less likely you
are to meet your desired goals of reachability in a
given amount of time
3. The fact that most carriers are literally dropping billions
and billions of SMS messages per day that are coming
across the e-mail-to-SMS gateways
There are commercial companies who specialize in these kinds of
emergency broadcast notification systems. For this function, you
want to go with one of these companies. Mailing lists are *NOT* a
good solution here.

When you have some control over the potential population (like a
University does over their faculty, staff, and students, or how a
company would have control over their employees), then an opt-out
solution of the sort you describe is quite reasonable.
Again, we get back to this issue where not everyone uses it that way,
and the feature can be sorely abused. However, considering
circumstances such as you have described, the feature is provided in
the code and is not currently disabled by default.
And, despite my own personal views, I realize the situation that
other sites may be in, so I don't agitate too loudly to try to change
