As alexp2_ad (happy birthday!) posted on the forum, Microsoft and Yahoo! are set to go through with a landmark interoperability deal which will allow users from each IM network to communicate with each other via text and voice.
MSN Messenger 1.0 originally allowed access to the AIM network, but AOL continuously blocked MSN - quote from BetaNews:
In 1999, Microsoft connected its MSN Messenger client to AOL’s AIM network - without authorization. The move let to a cat-and-mouse game of AOL cutting off its new competitor and MSN re-establishing communication with each update. Microsoft eventually gave up and focused on improving its client.
This move is a great step forward, interoperability is becoming more and more sought after by users. Read more at BetaNews, Reuters or ZDNet.
