Hey Todd,
We're about release a new cluster version of the Gluu Server. We've built API's for deploying docker-ized Gluu services. This new version of the Gluu Server leverages a product called "[Weave](http://weave.works/)", which builds a secure network mesh between the docker hosts.
We plan on releasing this as a commercial product, but it's currently free to test in beta. We'd love some feedback: [Cluster docs](http://gluu.org/docs-cluster)
Thanks,
Will
