DutchPIPE – PHP/AJAX Interactive Virtual Environments on Websites
With DutchPIPE open source software, web developers can make virtual multi-user environments. Each web page becomes an abstracted environment or location where visitors and other items on the page are visualized. This status is retained as visitors move around. A lot of real-time interaction is possible. The result: Persistent Interactive Page Environments. DutchPIPE uses AJAX and the DOM for the browser – it works without Java, Flash, plug-in or firewall adjustments. On the server, PHP 5 is used.
