I specifically would not like the Chatterbox to be Java. There are chatterbox clients for those who want a more 'realtime' approach.

Some reasons for not wanting it, not all of which apply to me:
Greatly increasing traffic for refreshes (which may trigger alarms to the proxy administrator for those using PM as a resource at work or otherwise raise questions.)
Low bandwidth connection getting hogged by constant refreshes.
May people keep Java & Javascripts off for security reasons.

It just doesn't seem to be a win. If you want the instant refreshes, there are clients available. If you don't, use it like it is now. No need to force everyone into the same mold.

That being said, in the spirit of TIMTOWTDI, an optional applet that could be configured per user would just increase the options for those who want it. I still urge you to look at the clients, though.
