> The futures returned by CommandDispatcher.submitOnCluster(...) contain the command execution results per member of the cluster.  However, if a given member has no active CommandDispatcher to receive the command, the resulting behavior is not handled, and the Future.get() will throw a ClassCastException.  This is because the RspFilter contained in the RspOptions as passed to the MessageDispatcher is not invoked for unicast requests.
> The API will likely need to be adjusted/documented to define what behavior to expect in this scenario.
