What if you have been scheduled to join or present in a Remote Demo, but find that the host is late and has not started the online meeting on time? (Has this ever happened to you?)
One simple solution is to ensure that the host grants alternative host rights to a second person (e.g., you) so that you can start the meeting even if the host is late. This is a current capability in many of the online collaboration tools (e.g., WebEx, GoToMeeting, etc.).
