On the Zend Developer Zone, Andi Gutmans points out some updates they've made to their PHP and RIA presentation by adding some new functionality to an existing application originally by Padraic Brady.

For our presentation on PHP and RIA (PowerPoint Slides) Stas and I improved the chat application originally written by Padraic Brady and featured in the Ajax Chat Tutorial. We added a number of capabilities to show some of the more advanced concepts in the Zend Framework. You can download the application by clicking this link, Improved Ajax Chat.

Among the updates are things like a seperation of data handling, the addition of logging capabilities (including an interface to the logs allowing searching, etc) and integration with several web services. Also included in Andi's post are instructions on how to get to these new features to check them out and what you'll need to get it all up and running.
