Vice/Multiple people chat

I think that it would be a good idea to have an option that you can chat with multiple people in the same "room" that way if you want to talk to multiple vices at one time without a third party looking on, and without repeating yourself, you can do so. Also if you have a conflict between two people and you wish to act as a meditor you can do so.

I think that would really help if an argument or misunderstanding would ever occur (which would neevvveeer happen ), but how much work would it entail and how easy would it be to use it?
