Here’s something to delight all you World of Warcraft fans out there: your favorite game is running on the iPad. But unfortunately, it’s being streamed via Wi-Fi from the game streaming server Gaikai, not running on the iPad itself. So far, Apple hasn’t prohibited type of software.
Gaikai is a game streaming service currently in beta. It would allow you to play games using a Flash client on any desktop and, apparently, a native client on the iPad (or iPhone, I presume). In theory, an application like this would allow any kind of game to be played in the iPhone OS without going through the App Store payment system, something that is not going to make people in Cupertino happy.
