Instant Messenger client. Free Browser Based Ajax IM.

Ajax Instant Messenger ("asynchronous javascript and xml instant messenger") is a browser-based instant messaging client. It uses AJAX to create a near real-time IM environment that can be used in conjunction with community, intranet, and social websites.
