Okay, here’s a web communications service called Instantstream that provides a system which has audio and video features. This system is “Streamphone”. Again, I am ashamed to say that I have never given a PowerPoint presentation, but this system has features that allow you to display synchronized PowerPoint slides, perform group calling and sales presentations, collaborations, chat and specialized web conferencing services for 1-12 presenters. It can broadcast to more than 5,000 viewers. There’s a list of subscription plans to choose from, starting from Video+Audio at $0.20 per minute or an Audio only subscription at $0.60 per minute. After you register for a free account you will get $10 free minutes.
