This is a neat idea. You could have a video game like NBA 2k act as the frontend for the data coming out of stats.nba.com backend, and simulate - in realtime - the actual games as they progress. If the latency between the frontend and the backend is reduced enough, you'll effectively have a "live" game played by simulated players that is more or less a replacement for the real thing. You could then charge people to watch your simulated games.
