Possible to trigger system events based on ip conflicts?

Hi,

Is it possible to trigger scripts/events based on IP address
conflicts? Something that can be used as a backup solution,
like a simple cluster failover, when one IP fails, the other
takes over and when the first comes back on line the second
one goes down (standby) and the fist one takes over again.
What is the simplest solution to that?
