Hi, My wife and I have been using the same iCloud ID for a long time. With iMessages and FaceTime, even if both devices have the same iCloud ID, you can choose a different "username" or receipient. So I can do FaceTime with her, using her phone number or Yahoo mail as ID. With Photo Stream, there is no such an option. The photos shared from her device are shared like if it is me (the account is under my name). And she cannot really share them with me so I can "like" and comment, they just appear in the Photo Stream menu without notification or anything. Any workaround or thoughts? Thanks!
