Few months ago before Windows Live Wave 4 was announced, we were first to tell you that Windows Live Messenger (the client application) will support interoperability with Facebook Chat. Today according to a blog post on the official Inside Windows Live blog, Omar Shahine (Principal Lead Program Manager for Windows Live) mentioned that besides being able to talk with your Facebook Chat contacts within Windows Live Messenger, once you have connected the Facebook service to Windows Live, you’ll also be able to talk to your friends on Facebook Chat on any Windows Live web properties!
Omar also posted a screenshot showing Facebook Chat on Web Messenger in action:
Facebook Chat is currently not available yet and will be rolled out later in the year. We’ll let you know as soon as we get more news about it, so stay tuned!
