GTA VC Multiplayer/CO:OP

[-Kenneth-]

Is it possible to create such a thing? I saw a lot of versions like - Split Screen, MTA, but i'm not thinking on them. I'm talking about the real thing, the place where you and your friend (Another Computer) can play whole storyline together, maybe the other player can't make full appearance on cutscenes, but for gameplay it's big move! It's difficult to make, but not impossible so i want to hear opinion of other members on this topic.
