You'd naively calculate per-player requirements at 720p to be 1,000,000 pixels/frame x 30 frames/sec x 10x rays/pixel == per-player you need 3 giga-rays / sec (+ video compression hardware). Maybe the video compression blurs stuff enough that you get pseudo-aa for free, letting you chop some of that 10x off. Either way, their 'fusion render cloud' is supposed to be targeting the petaflop range, and @ an extremely generous 1ray = 1flop calculation (bear with me) you'd be able to handle ~333,333 simultaneous players (720p frames) @ 1 petaflop (and with more-realistic flops-per-ray you're looking @ a lot fewer). You'd definitely need a breakthrough.
