For the failover, configure both servers to report to each other it's situation. Configure both servers to trigger a script when there is an alert. Except one of them is the master and is always sending out the alert. The other (the slave one) first checks the status of the other server (a simpel wget of the status page can be enough) and only sends out the alert if this page is not green.
I would rather:
bb $MASTERDISPLAY 'query $MASTERDISPLAY.bbd'|grep -q ^green || enable_hobbitd_alert
(where implementation of enable_hobbitd_alert is left as an exercise for the reader)
I was thinking the depends=($MASTERDISPLAY/bbd) syntax, but on further inspection, I don't think that will cut it.
