While Tal Ater was working on his Green Any Site Facebook application, he stumbled across a javascript object called Video Chat. This object had properties that were referential to Skype's video chat features, pointing to potential video integration between the two sites in the future. While the application wasn't there every time Tal loaded the page, he thinks that Facebook could be "bucket testing" the feature.

The object also tests for plugin functionality using the Skype SDK, which further points to a collaboration between the two popular online services.

Tal has helpfully provided a link to the code on Facebook's own servers.
