I know it’s been a long time since this post was posted. But Zen streaming allows to stream the game to targets. So it doesn’t pack the game in a ship-able form. It seems to be used for faster iteration between cooking and playing the game on the target device. But it’s not the same as playing the game from a pak project. It’s like game streaming in your local network.
Please correct me if I am wrong but that seems to be the case when I read the documentation.
