Is it possible to control what audio/video is seen/heard on another user's
computer? example: a web conference where the speaker is site 'moderator' and
people watching the conference can submit questions. by default the users are
not visible to other users, only the speaker. the speaker has the ability to
'activate' a user's a/v so every else can see/hear when they ask a question.
Is this possible? If so, any coding examples/tips? Thanks...
