We started out with no-login, but without the ability to save emails and have some kind of session persistence we ended up with a lot of abandoned conversations. It is pretty much no-login now, you can just send an email and go, even if you don't have an account. But we store your email and previous conversations. Great idea, we are actually doing that :). If you don't participate in the realtime chat you get an email summary of the messages you missed. And yes to this as well, if you cc go@chat.cc on an email thread all future replies get funneled into the conversation.
