Free MobileMe for FaceTime?

Steve Jobs at the presentation of the iPhone 4 showed video calls. Product page . In particular, one of the features is declared a seamless search for matches from the address book and addresses of other service users.

For calls to one Vaymaks operator, we solved a similar problem. There were two solutions: temporarily sending emails and phones from the address book to search for matches, and searching and linking stored synchronized contacts on the server.

Apple already has an AppleID that the user has for purchasing apps, music, and books, and there is a paid service to sync all MobileMe. I would assume that a free plan will appear there and, explicitly or implicitly, the search will go through the synchronization of contacts, and also that you can specify the AppleID manually as a type of email.

What do you think?

Interestingly, in the pre-release firmware for 3GS there are no hints of video calls, i.e. This will be a feature of only the new device and the details will be known either at the passing WWDC, or after the launch of sales.
