What I like about Campfire is looking back through the transcript is easy - even for the times when you have left the room. Plus it has the ability to star parts of the conversation so you can see the important points as you scroll through. So you can use it as a synchronous "have a chat now" tool - or as an asynchronous "leave a message and I'll deal with it when I return" tool at the same time.
