Remote Desktop Pointer
Provide the ability for a remote user to click on a random location within the remote screen and all users can see what was clicked. Maybe time-out within a few seconds. A simple MVP for this might be to use the same functionality that currently exists for remote control, except without the "control".

Imagine trying to help navigate someone through the depths of the Azure portal and you keep saying "no, click on that, no click on this..." If you had a remote pointer to just show them where, you could improve the remote support experience.
The meeting presenter should be able to assign to a user the role of "assister" and that person can then move an additional mouse pointer (crosshair, etc) on the presenters screen to help with navigating through the UI. Perhaps a user can request the role of "assister" and the presenter can be prompted as well to accept the request.
