Hi Jared, Currently there is no support for adding and removing zookeeper nodes dynamically. See: https://issues.apache.org/jira/browse/ZOOKEEPER-107
We're currently working to add this feature. However, AFAIK there is no intention to support transformation between standalone and multi-node modes, only membership changes in multi-node mode.
