App controls third party app - requirements/submission

We have developed an application that controls Adobe InDesign from the outside via apple event connections.

The app is completely sandboxed - and working via temporary exceptions.


We were wondering if there's anything special to take into account when submitting for review:


- The app needs Adobe InDesign to work - is that a reason to be rejected?

- How to tell the requirement to end users?


Thank you

Pat
