In my previous job where we developped our own PDF interpreter (neither based on Adobe owns PDF lib or Print Engine) we only needed InDesign in short occasional burst, mainly to produce test files when new PDF features were introduced, or to check some issues reported by customers. Switching to the CC model for us made sense as it saved us money.
And in my current job we only need to use Adobe applications to generate demo files for tradeshows and sometimes private demos. So, we never require a full-time license. And we can use it as an alternative to a floating license as any of us can log in to use one of the application before logging out once finished. However now that I think about it I am not sure whether our marketing team switched to the CC model or have been using CS 5 or 5.5 the whole time. Considering they use it much more often than us it would make sense if they did not use CC.
