How to disable VMware HA Datastore Heartbeat

I Was asked today how to disable Datastore Heartbeat in a VMware HA cluster. My first response was that this was not possible, but it turns out that there is a workaround.

Duncan Epping published a Blog last year about it: http://www.yellow-bricks.com/2013/02/25/how-to-disable-datastore-heartbeating/

But i agree with the comment in the blog, that this is nothing you should do in production.
