fallback alert service

[Joost van den Broek <joost (at) seat-ibiza.nl>]

Hi,

Maybe this is already possible, or it's a feature request for the next 
release. Anyway, I'd like to have some kind of fallback alert method in 
case the used alert service is down. E.g. if I need to be alerted 
through a sms2email gateway which is down, it should use the next sms 
gateway. I figured it would be simple if the same dependency system 
could used for this purpose.

Thanks,

Joost
