Meetingl is a free service for hosting video conferences. A Meetingl conference room can be created in less than a minute. To create your room just go to the site, click "New Room," name your room, and send out invitations.
To broadcast your video and audio select "allow" when you're asked if you want to grant Meetingl access to your computer. Mettingl is flash-based so you and your conference participants will need to be on a laptop or desktop computer.
