If you are a coder, then you could go this way.
If/when you have something useful, please share it with us - either via the code or/and via a link to your calendar.
For those of us, that want it to be easy when upgrading ( using the standard solution) , and therefore want an extremely flexible solution where most things can be solved via settings, then I think that in the near future, we will be able to use the display also for login, and for letting the display use the credentials for the user, and eventually create/edit events from/via the display.
This could be a great enhancement for using the calendar on mobile devices.
This summer, it has been hot here in Europe - so is the calendar.
