Thanks for the Informative answer, you've tackled all the different options
I'm only interested in one scenario you've mentioned at the end of your post
"As for if the MSDN rights extend to clouds that are not Azure, I don't think that has been clarified."
in my local data center we've purchased MSDN licenses for development/testing purposes (not Volume License) , we would like to use the same keys for vCloud Air, i've uploaded my own templates so i don't need the public catalog services.
thanks
