Implementing Limited Multiplayer

[plinyvic]

How feasible would it be to implement a multiplayer function into the battlescape? I remember there being a utility for xcom in dos that allowed two users to play as each side, but that also involved closing the game and restarting it. Would it be possible to somehow make this work in openxcom?

As a fork I would estimate 500 lines of code, but no one will want to update it.
