Ok, in Direct Play, can the Direct Play message callback be implemented as public member function of a class? Also, in a multiplayer game, should updates on game objects be processed as soon as they are received, or should you queue them and process them in a batch fashion as a step in the game loop? The same for updates to players: should updates be sent out as soon as an object is modified, or should all objects be processed first, then send out all of the updates in batch fashion...?

Does nobody have an answer for me?
