I'm hearing through the grapevine that there is the strong possibility that as early as tomorrow Yahoo and MSN will be even closer than ever. The two have been getting rather cozy in the area of Instant Messaging. Now it seems within the next days or so the two will announce interoperability between IM clients, both dubbed messenger.
Since both use SIP that likely also means that Voice chats between both networks is possible.
Somehow with a move like that, and a potential AOL/MSN alliance it is starting to look like we will be having a three way dance between the Portal IM players, Skype and Google.The move comes right on the heels of pal Michael Robertson's launch of the IMFederation today.
