I understand that when using XMPP on AppEngine, the account used is based on your app_id (i.e.
your_app_id@appspot.com). Now, in the past, when I used XMPP through other services, I created my a new account for the app, which allowed me to customise it in terms of the name and profile picture shown on the client. That made messages coming from the application look much more professional - having the default blank picture showing up on Google Talk makes it look like a half baked solution.
So, my question is, is there anyway to customise the
your_app_id@appspot.com account in the same way you do with a regular Google account, particularly when it comes to changing its display name and profile picture?
