Myung and I have been talking about this for a while trying to figure out how we can make the game more accessible to spectators. Even if we have two stream setups, that can end up diluting the experience because the commentary becomes two people shouting over each other and you still don't see very much. What we want is a centralized video feed, which can switch between the two video feeds as necessary, but the technology to do this quickly and easily on one box might be beyond the budget we have. It would be perfect for the commentators, perfect for the stream, but very difficult to do.
That said... I really really want to have this available by next NCI.
