If I remember correctly, what I noticed about this plethora of carbonite comm channels thing is that it tends to happen when the client-server connect is bogged down, and responses don't get back and forth in a timely manner. The root cause can be a problem in the client, a problem in the server, or a problem in the 'net itself. I don't know which it is right now, but it's certainly happening - it's why people are stuck at the login screen for great lengths of time, or have to "force quit" the client to get out of the game. In such a case, it's unlikely to be a problem soluble by addon authors.
