Just wondering if we might one day see an Cloud Based Invite To Edit feature similar to the Illustrator and Photoshop feature for InDesign? I assume this might come when there is a iPad capable version for iPad? While it is not needed all the time I sometimes have to share a file to be edited by internal people in a company and it would be great if it could be shared and collaborated on so there is one master version of the file instead of sharing and then having an outdated file after they have done updates or changes.
