I just published a tool I have been working on to very easy send push notifications from Naemon, op5, Nagios or Icinga as a few examples to your Android, iPad, iPhone or desktop using Pushover
You can find notify-via-pushover on my Github page: https://github.com/jryberg/notify-via-pushover
Please feel free to give me feedback and feature request if you are missing something.
