I had this idea of adding the ability to run
application(s) in case of a severe weather condition.
it was origionaly for invoking growl via growlnotify
(but i see somebody has already submitted that idea,
good), but i realised it would be useful for other
things, like running a automated script that updates
pages on a web server, or (incase of power failure,
etc.) running a script that puts information in the
system log, so if the system goes down, the user will
know it's because of a thunderstorm knocking out power,
Also, you could pass the details of the event via
stdin, so it (the app/script) could parse it somehow,
to get useable data out of it.
