There is supposed to be some "Notification Sync" feature in iOS 7. I don't see it. Apps like iMessage have always worked since iOS 6: I get notifications on both my iPhone and Mac, and when I read it on one device, it's read on the other. That works fine. But apps like FaceTime never work. I get a call on both my devices, but which ever one I don't answer gets a "Missed FaceTime call" notification. And some other apps like Facebook don't sync either.
