Acting on a promise from July, Skype has rolled out new test versions for Macs and Windows that give both of the apps support for full Facebook video chat. Both an updated 5.4 beta for Mac and 5.7 beta for Windows let users make a call from their own Facebook accounts inside the app to others' without one or both having to go to the web. The only stipulation is having a Facebook account linked to Skype to get contacts.
