Skype released a beta version for Windows with support for Facebook Chat. They are doing it through XMPP directly from Skype BETA Client.
Once again XMPP moves forward in becoming the universal bus for 'realtime' communications.
Companies that are not understanding the importance of being 'realtime' will soon realize that their time is gone.
Hopefully in the future we also have support for other open alternatives for Audio/Video Communications on Skype like Jingle and Jingle Nodes. Like Google did adopting the Standard Jingle.
