All you have to change will be that the enet_send_pos/ang will have a 3rd parameter => everywhere you call that function in the script, you will have to add a 3rd parameter. That's all.

@Pappenheimer: The new demos are currently in internal beta test. They show most of the features of ANet Professional. I think I will start with an own multiplayer game after finishing this last update. It will have a playable demo so you will see ANet in action.
