I would like for all the users of a Hub to be redirected to the same instance of JupyterLab, as opposed to each user getting their own instance. I am planning to start working on a Spawner that will do this; however, I am wondering if anyone has already done this. Is anyone aware of an implementation that I can use?
Also, please let me know if anyone has any guidance on how to best implement this. For example, could this be implemented as a “service”?
The general idea here is for multiple students to join a teacher for collaborative “office hours”.
There’s an example in the JupyterHub docs of running a shared notebook as a service
In conjunction with c.JupyterHub.default_url you might not even need a custom spawner.

@manics Thank you. I got it working; the implementation seems to make sense. I can start the service as a non-privileged user and everything seems to work perfectly - the logs don’t indicate anything isn’t working. As you suggested, I configured default_url to send authenticated users to the “classroom” service and it’s working as expected; it doesn’t seem to be starting user servers, which is nice. Collaboration has been working perfectly too.
Now, I just need to containerize it and we can have collaborative office hours… 
Thanks again for all the help you have given me over the years. If you’re ever in Ann Arbor, let me know if you want to drop by for tea.
