Microsoft and Yahoo have reached an agreement that will link their instant messaging networks, allowing MSN Messenger to exchange text and voice messages with Yahoo Messenger users, and vice versus.
According to the source, the deal includes the exchange of text and voice messages. An announcement is expected from both companies on Wednesday.
This deal is a landmark in interoperability. While a number of third-party instant messaging programs such as Trillian offer multi-network support, they still don't allow interoperability.
Of course, businesses running Microsoft Live Communications Server (LCS) have had the ability to interoperate for several months, but this level of interoperability has never been available to consumers.
