Frank Field, I got sent this link by one of your sales guys on a query about deploying an app from the App Studio.
Looks to me like the app studio has been updated since this blog was written and now needs a revise.

Stumbled upon this one:
The link is 404 and the event was back in 2015. There are no comments.
