Open Stack

I have the impression that more and more people try to run OpenStack
in a "mixed-releases-mode" and face some troubles to understand how
the capabilities and limitations look like. For example, the reporter
of [1] runs a nova-conductor (Juno) with a nova-compute (Kilo). I tried
in comment #3 of [1] to rationalize if this is a valid setup or not
and I failed... 
If someone with more experience and knowledge could help there and
clarify it also for other users in the future, that would be awesome.
