Yahoo-MSN IM interoperability still a dream

When yahoo launched Yahoo Messenger Beta v8 and MSN came up with Windows Live Messenger, I thought maybe Yahoo-MSN IM have become interoperable. Even though in Yahoo IM I was able to add an MSN id, WLM didn't get any request. Seems like the two giants failed on first attempt.

Yahoo and Microsoft said late last year that they would launch a service in the second quarter of this year that would allow their customers to send and receive messages and share buddy lists between the two instant messaging networks. With the second quarter come and gone, representatives from both companies say the interoperable service will launch globally very soon.
