Okay, one last message and then I really need to get back to work...

* There seems to be an issue when a user B who had previously joined a
shared session by user A ends that session and then later tries to rejoin
that session. Arithmetic then gets stuck at the "Joining shared activity"
screen and while the network view indicates that user B has indeed joined
the activity it never moves to a state where it can actually be used.
