We have two front end servers that alternate the notification role.
Using a pair of Nokia GSM mobile phones attached by their USB cables
to the servers for charging and for the data connection.  These are
being operated by gnokii-smsd.  We insert a notification message into
the database queue via a perl script that is called by the
notification handler.

The only trouble we've had is from before we switched over to
gnokii-smsd, and were just using gnokii.  If two notifications came in
at *just* the right time, the phone's USB port would hang attached to
a zombie process, and we'd have to reboot the server.  So, once or
twice a month we'd have to reboot one of the servers.  gnokii-smsd
solves that problem by queuing outgoing messages in a database.

Personally, I find that SMS is about as reliable as email for timely
notification.  However, we also offer jabber notifications, and I'm
working on being able to hit analog/celluar pagers from Nagios.
