If you've created a CRM (2.0-style) cluster, then you can set the 
failback to occur at a certain time - by setting a time-based policy for 
failing back at that time (like between 2 and 3 AM).

We don't currently have a policy which lets you decide exactly when to 
fail back yourself.  But, you could write a program which detects this 
condition, and modifies the policy, then waits a while, and changes the 
failback policy back to "don't fail back".

Andrew could give you the details on how to do both of these options.
