I recently heard of an interest from one of our customers to integrate a <i>meebo / meebome</i> (adjax im) into their eZ Publish Commerce website.
From: http://blog.meebo.com/products?o
<i>"meebo me is an embeddable IM window you can drop onto any personal webpage – it lets you chat with site visitors in real time from meebo.com. Visit http://meebome.com to build a customized meebo me widget. You’ll be chatting with people on your site in no time!"</i>
The problem is that this project requires chat and advanced forums and i have really few time to code my own forums and integrate a chat. Think that for this project i will go with drupal and see what happends. I know nothing about drupal but at least chat and advanced forums are integrated,
