An Update on Messenger for Mac

I wanted to take a moment and share with you the progress we are making with Messenger for Mac. This year we successfully delivered Audio and Video (A/V) support in the corporate service (works with Office Communications Server) of Messenger for Mac 7. We are now on the path to implement A/V support in the personal service (which will work with Windows Live service), and uses the same protocol as the corporate service.
I’m glad to say that the upcoming release of Windows Live Messenger, currently in beta, delivers the new A/V protocol that enables us to deliver A/V support in Messenger for Mac. It is cross-platform compatible and will work with Windows Live Messenger. This is a huge milestone that will enable us to continue moving forward with Messenger for Mac development. 
We are very excited to be able to bring A/V support to the personal service. Our plan is to deliver a beta version of A/V in 2009. We are also working on additional features in both the personal and corporate service of Messenger for Mac for the next version of Messenger. We’ll provide more updates and details in a future blog post.
