The freedom of not "being there"!
With software like GTT, you can really be at the meeting without being there! You can be as incognito as you like, and join the meeting as needed, doing whatever you wish in comfort and privacy when not needing to be front and centre. Its also easy to run the meeting, just join in, monitor the meeting, "chat" to the group or specific attendees during the meeting... It may be better than really being there in public performance mode.
