Even before Skype revealed a deep Facebook integration last month, there was speculation that Facebook might add Skype video chat functionality within the social networking site.

Skype Video Chat Coming to Facebook?

Although that hasn’t happened yet, Facebook application developer Tal Ater has rekindled speculation around the idea in spotting a “VideoChat” object in Facebook’s code . Interestingly enough, the code has several properties that refer to Skype and Skype user IDs.
