Live writing and chat?

Recently I've seen a story I read do a live writing with a chat. If you happen to read it, you probably know what I'm talking about.
This isn't going to be my official post asking people but I want to know if the few of you who read this might like the idea.
I'd most likely have special things I share with you, you can suggest ideas and I'll even have the cypher to a code I'll end up implementing to the story
