Isn't the requirement of providing two nameservers when registering
a domain to ensure redundancy in case one is down/unreachable/etc.?

Having two instances of BIND (bound to separate IP addresses) on
a single machine throws this redudancy right out the window.

If one only has one physical nameserver, there are web sites devoted
to matching up people who agree to provide secondary DNS for each
other.  This has the added benefit of having your nameservers greatly
separated (both physically and network wise).
