cPanel/WHM droplet clustering?

Is anyone using cPanel/WHM to cluster multiple droplets? I cannot seem to find anything more than references to it being done, but no details on how to do it or discussions about it.

I’d be interested in pros and cons of doing this. Does the cluster end up being a master/slave set? Does each droplet maintain its independence? What else should I be considering if I go down this road?

My main reason for wanting to do this is to simplify management of only TWO droplets at this point - but planning on perhaps adding several more in the near future.

Primary use of current droplet running cPanel/WHM is MySQL and Wordpress sites. The other droplet is running zPanel and is used for Icecast and Shoutcast streaming audio. Future droplets will likely be more WP sites.

Thanks for any input.
