In a blog post today, Facebook app developer Tal Ater claims to have stumbled upon a Javascript object on the Facebook website called VideoChat with a number of properties that specifically mention Skype.

Facebook was previously reported to be testing a video chat feature back in May 2009, when similar code (not featuring mentions of Skype) was found. At the time Facebook said it had no plans to release the feature to users.

That'd just about be gg I think.
