Facebook app developer Tal Alter discovered the code, called VideoChat, while digging around during development of his own application. The code "appears to have everything needed to introduce video chatting functionality," he said.
Even more telling are the portions that mention Skype directly, which he believes indicate future integration with Skype address books or using your Skype ID to chat with Facebook users. The code also checks for ActiveX or Skype SDK plugin support, Alter said. [Green Any Site via Techmeme]
