What I do is have an invisible frame that checks the timestamp of the last update to the chat against your last refresh timstamp. If it's superior, I refresh the chat list. I actually make this check without a call to the database, if you have 100+ chatters, check calls to the db can become heavy. I just have a file that holds the last update tstamp and read this file. The check page refreshes itself every 20 seconds (plenty enough for a chat I realized) and has the last given value of a refresh.
You can see my chat at http://zc8.com, you have to login though.
