I’'ve finished working on an open source chat Application based on Smack API. It is 100% Ajax (Google Web Toolkit) which is using Smack API extensively. It is well tested with Google Talk and it supports all major browsers such as Internet Explorer, Firefox, Safari, Mozilla. Anyone interested in the application can download source code at http://cde.di.uniba.it/projects/livejabber/ under MIT License. Anyone interested in the application or want to contribute, can contact me at firstname.lastname@example.org .
