The rumors for Skype & Facebook are happening again with a snippet of Facebook code as pictured below:
Tal Alter, who develops Facebook apps discovered the code dubbed VideoChat while digging around during development of his own app. He said that the code "appears to have everything needed to introduce video chatting functionality".
Need more proof? There's portions that mention Skype directly, which Tal believes indicates future integration with Skype's address books or going a bit further and using your Skype ID to chat with Facebook users.
