Pandion is an instant messaging client for XMPP and Jabber networks. Pandion is designed for usability and standards compliance. Because we think security is not a feature but a necessity, Pandion automatically encrypts your connection to XMPP servers. Pandion makes it simple to use cool features like custom emoticons, avatars, and text markup. You can easily extend the functionality of Pandion by installing plug-ins. Creating your own extensions requires only some knowledge of HTML and JScript.
