Racing on twitch with Beyond Chaos

I can screenwatch twitch while streaming. Skype could be a good idea to talk while I'd like to comment via Twitch (hold keyboard button to talk). I don't think there would be a way other than skype to discuss, unless there's a way all three (or four) can comment the race at the same time other than on their personal twitch page.

For the multitwitch url, you just need the twitch users of all racers and all streams will be on the same page. Example: http://multitwitch.tv/JackimusWedge/Lockirby2/madsiur
