Gaikai: Delivering instant MMOs to your browser - Joystiq | Wizard101 (and anything related to this wonderful game) | said: "...Gaikai is refining is a better way to offer progressive downloading through what Perry calls "cloud delivery." Players might know progressive downloading in titles such as Wizard101, where the bare-bones client is saved, a player heads into the game, and the rest of the data continues to download in the background. Gaikai's version of this will eliminate the need for a saved .EXE file to offer the fastest speeds possible for publishers interested in this approach."
