Ghetto, but brilliant.

Much like hanging an old cell phone off a Nagios server via serial cable 
so it can send SMS alerts directly, as opposed to worrying about 
connectivity failover, etc (getting signal inside a datacenter 
cabinet notwithstanding)...so at least when monitoring from the inside, 
you know the difference between a link failure and a power fail.
