Accumulo also has a pluggable load balancer that could be used to balance with rack and data-center awareness. This can be done using the currently released versions of Accumulo.
What problem are you trying to solve, exactly? Are you concerned about durability and availability issues like disaster recovery in the event of a datacenter failure, or more about optimizing performance under the constraint of non-uniform network topology?
