As a user, I would expect the functionality to be able to download a Mobile Map Package directly within ArcGIS Navigator which has been shared with me via a group from another ArcGIS Online organisation. Currently I must either a) sideload the MMPK onto the device, or b) download the MMPK via URL, however, this is not a streamlined workflow for organisations wishing to share and provide constantly updated MMPKs to customers.
