Exactly that - slaves monitor the master (and vice-versa) via a nrpe-wrapped check_nagios that checks /var/spool/nagios/nagios.log (runs every minute). This is where the event handler is kicked off on any HARD state change. Since any large-scale problem will result in moderate-to-severe latency as checks timeout and reschedule (especially if send_nsca is timing out on passive result submissions as well), there's also a cron job that runs every two minutes that basically does the same thing, just outside the guise of the actual Nagios daemon. The only drawback is it can't self-demote (or you'd be spamming the external command file every time it runs). Prompt self-promotion is the primary goal here, so some latency in self-demotion is perfectly acceptable since the only risk is receiving redundant notifications from each slave for any globally-monitored hosts.
