VideoSift highlights a clip on the YouTube from a few months ago where TechCrunch demonstrated OTOY, one of the upcoming cloud-based gaming services. They show Grand Theft Auto IV being played on a laptop streaming from the cloud, showing the game to be generally playable though the demonstrator's estimate of the lag is a quarter second, or a whopping 250 ms. The game also has no sound during the demonstration, being one of the things the OTOY folks were still working out. Thanks Ant.
