At this point, JupyterHub doesn't offer anything beyond what you can do
with filesystem permissions - no cross-user notifications, or anything. The
multi-user context has no awareness of what notebooks are open or by whom.
We do plan to add some amount of sharing functionality to it, but we have
not yet decided how that should look or what we can/should provide
before/in addition to live collaboration.
