Skype has updated its desktop app for both the Mac and PC and now offers the option to made video calls via Facebook to your Facebook contacts, with the launch of Skype Beta 5.7 for Windows and Skype Beta 5.4 for Mac.
Initiating a Facebook-to-Facebook call from within Skype is quite easy; all you need to do is connect your Skype and Facebook accounts. Then, select a Facebook friend and hit the video call button in Skype- your friend simply picks up the call from Facebook. This new feature lets you maintain social connections with your Facebook friends and compliments previously announced features such as being able to see when your Facebook friends are online, read their status updates and IM them all from Skype
