AJAX Jabber Module for Website

This is a very small project, requiring development of an AJAX module to be placed on the website http://solidaireinc.com. This module will be a way to capture our visitors as leads. To do so, it will have to interact through the Jabber network with a designated Google Apps e-mail address. It will need to replace the short contact form at the top left of the page if that e-mail address is online. If it is offline, it should send an e-mail notification to the address to notify that someone is visiting the website. ## Deliverables If there are any 3rd party apps that would be able to achieve the same or similar ? functionality, I would be willing to consider them.
