> Do localhost (127.0.0.1) TCP sockets work between two different apps? Yes, and there are systems like Audiobus (http://audiob.us) that use it for live audio streaming between apps. The tricky part, I think, is keeping both apps running at the same time since one will be in the background. Audio apps can do this because iOS lets them keep running to play background audio. This doesn’t sound relevant to Alex’s question, though, because he presumably doesn’t want both apps to have to be running at the same time to share the data. > Now here's why sandboxing really cannot hope to keep two apps from > communicating: What you say is true, but I don’t think it’s been Apple’s goal to keep apps from communicating. After all we already have mechanisms like registering URL schemes and opening URLs. Apple is just limiting the types of communication to avoid channels malware can use to attack other apps. —Jens
