There is still a problem there: when you hit the Share button, there might not
be a connection that you can use for collaboration. The activity can tell that
this is the case, but can't tell when sharing does become available.

Ideally, we would enable and disable the sharing button at appropriate times.

I agree we should delay as much initialisation as possible if it saves us
startup time.
