I would like to warmly urge the introduction of audio channel in double directions: from desktop to smartphone (used as webcam, audio and video source) and from smartphone to desktop. If the smartphone used as a webcam is called “mobile” but it is impossible to send verbal indications of movement from desktop, this is rather contradictory 
It would also be essential that all devices connected as sources had a shared audio channel in the same streaming transmission, with the possibility of also closing/opening this audio channel from the desktop application, from which you have direct control of the transmission.
I modestly believe that in this way your application could make a big leap forward and thus satisfy many professional usesw. Do you think these functions can be realized?
