Hi Eve Looking at the WRAP oriented comments in the spec, here are some comments / questions: Note WRAP doesn't seem to say HTTPS is required for the user authorization URL; is this a bug in the WRAP spec? If not, is it a good idea for us to profile it in this way? Finally, is this the right p

As was discussed on the OAuth list, desktop apps can NOT be secured, so there is no way to ensure it really is the desktop app you think it is. For most phone platforms, this is also the case. For totally locked platforms where the app is part of the OS (xbox, PS3, some phones, settop boxes) --
