Yahoo IM in Yahoo mail

Just as Google users use Google talk and Google mail services in the same window soon Yahoo users may be able to use the messager and the mail service in the same way as google users are doing now. Yahoo is planning to integrate the two services so now you no longer will need to download the Yahoo Internet messanger to user system. The company has demonstrated this service at Web 2.0 conference, Garling House publicy. So, its for us to see now what other major players like msn, rediff etc. do, will they take the same step.
