I have to write a live help system to be shared among all of the web sites we power. I figure I can do most of it easily enough through asp.net, but the one feature that I've seen in many of them that I'm not sure how I'd pull off is displaying a message when either party is typing something. I've been on numerous chat systems and when the person I'm talking to starts typing, it displays a message saying that they're typing. Does anyone know if this is accurate and if it's possible to tell if someone is typing a response or is this just a canned status message that comes up after so long a period of inactivity? Thanks.
