What failure condition are you trying to safeguard against? A full data center failure? That's when you would lose your entire cluster and need the DR to kick in. Otherwise, you could deploy such that an entire rack failure or even a row failure won't take you down. Just span across multiple racks and rows. For a full data center failure, the current replication scheme only gives you asynchronous replication for reasons Ian mentioned.
