And it's probably worth noting that a major design goal of dnsmasq is 
to remain simple.  It targets (and nicely fills) most common needs, 
and unlike many network services, you don't have to devote a lot of 
time to learn how to run and manage it.

I'm sure if Simon can figure out a simple way to do failover, he 
will, but I don't expect it. :)

Right now the best option for failover seems to be ISC DHCP 4.3, or 
possibly Kea for the adventurous (a failover protocol does not seem 
to be implemented yet, but lease database sharing is possible with 
another possible point of failure: mysql or PostgreSQL.)
