Question: How would all 4 masters know to reload a zone when you change it?

Also, would you have any Single Points of Failure in the switch itself or in
any of the components in the network path from any potential client to the
switch?

If you really care about availability, it's usually best to have slaves
situated in diverse locations, network-topology-wise. Otherwise, if all of the
authoritative servers are sitting on one network -- even if it's a totally
bulletproof network -- failures in other parts of the INTERnetwork can render
all of the authoritative servers for the zone unreachable, which is a Bad
Thing.
