Thanks Luke, sorry for taking so long to reply - I planned out my response in my head and then completely forgot to actually type it!

Your premier problems sound very similar to the issues we have been having. Particularly with inDesign, which can be solved in a similar way using the package and IDML options. 

With the software constantly changing, as you have mentioned, we envisage all sorts of problems with training materials going out of date faster than usual and that sort of thing too.

Have you had any complications with the licensing and the shift to user based cloud type stuff instead of machine based traditional?
