PrimeFaces features Ajax push/comet capabilities and the TouchFaces mobile UI kit. Integrating these two feature helps implementing push/comet based applications for mobile devices such as iphone easily. A sample chat application is created for demonstrating the communicating between desktop browsers and the iphone mobile app. Also there's a short screencast presenting the apps in action, http://cagataycivici.wordpress.com/2009/10/12/mobile-ajax-push-for-iphone-with-primefaces/.
