I didn't think we could have control of a VDC to the point that we know that no one is creating vapps on it, from my thinking, it would only work if we had individual sandbox VDCs. I was also looking to avoid building slow tests - setting up and clearing down an environment would be slow to run and prone to errors around clean up.  

It seems unlikely to me that someone would run the diff integration test config file through the launcher. My feelings where that if they did, we'd see the problem and could fix it then, by investing in different tests at the time it's become a problem (I appreciate that I won't be around when it does). 

However, perhaps I could change the test so we use a UUID so we make the likelyhood even smaller? Would that be enough for now, or is that still creating future problems?
