The AppId defined in AllJoyn spec is a globally unique identifier for the application. My question is : Should the same application running on different devices have the same AppId? If it's true, we should not generate the AppId at run-time, it will cause the same application on the different devices have different AppId.

For people who didn't subscribe to the mailing lists, here is an answer from Dave Thaler to the same question:

The spec doesn’t say. However, our interpretation is that yes all instances should have the same AppId. If the same application runs on different devices, they will have a separate public key in security 2.0 though, since they’re claimed separately, so the public key is more like an application instance identifier.
