<blockquote>
Only organizer/initiator shares his screen.<br>
Screen is one-way; however audio is two-way.<br>
Organizer can speak with all users.<br>
All users can NOT only view organizer's screen; but also they can talk with him.<br>
Users can NOT hear/talk each other. It is one-to-many kind of topology; it is NOT mesh or many-to-many.
