OpenFeint PlayTime announced, the multiplayer with real-time voice chat for IOS

OpenFeint, perhaps to counter competition from the GameCenter Apple announced PlayTime, a function that plays in real time with other players, complete with voice chat.

 With PlayTime users can then play with other players online to all games that support this feature. In addition, during the game, you can talk via voice chat with other users.
The function will be implemented soon.
