Mark,

The two classic cases I see which justify our use of trying multiple IP
addresses is:

    - network interfaces which fail.  So the host is up but the interface
    is down and people cannot or do not want to remove the old interface
    address from the domain system during its two or three day repair
    period.

    - transient network routing problems which people are having trouble
    tracking.  So one address works sometimes and the other all the time.
