In general, this means that one node in the cluter is inactive. Sort of a cold standby node.
However, you can get really fancy and have nodes in a cluster perform different tasks (a web and a database server), but let nodes do a failover to each other. This is what's called mutual cascading/takeover. This way, all your boxes are active, but in case of a failure, you get a performance penality.

People wanted to look at code, but I don't feel anybody whould gain much from what is written so far. Stay tuned.

Linux-HA uses the same trick to do network failovers. Send an ARP request to the broadcast address and let the nodes on the segment learn the new address. Most OS's will then update the machines ARP cache, and not wait for the ARP cache to timeout.
