We were trying Google Hangouts Live a neat system that allows the easy recording of the interaction and is then posted on a youtube channel. The issue 1. when you are running hangouts live anyone can watch whilst you are live. After the Live show you can then if you wish make the recording Private. But you can not make it private whilst live. 2. If you run a standard hangouts only 25 people can join in and It doesn't record the interaction . You can however use 3rd party software to record the show then later upload to you tube.
The solution we are looking for
To run a live private hangout only those invited can watch then uploads the interaction to youtube but is restricted to only the people we want to see it.
