We have a use case for having the exif datastream available and indexed for the large image solution pack and image solution pack. This would be similar to the usage in the audio solution pack. Alan had mentioned that in that instance (audio_sp) it is not configurable. He had a concept for a configuration interface which may add to this discussion.
We will be wanting this at UPEI so I'm raising it here to see if it's desirable to add it to the core code base(s)
