Application configuration / solution

[HarvThain]

I have the following application and need to know what product would be best suited to this. 

1. We have a group of respondents who will be hosted by a couple of hosts to discuss various subjects for market research purposes. 

2: We need to be able to share the above session with another group as "Anonymous" observers (we do not want the respondents to see names or brand of the observers). These observers are from the manufacturers or suppliers of the product or service being researched. 

3: These observers need to be able to chat between themselves and the session hosts so they can direct the session hosts on the direction of the discussion in the main session. 

4: We need to be able to record the session for post session review with the client. 

Which product / solution would do all of this? 

Can we achieve this on the basic version setting up 2 separate rooms?
