Concerning the upside view, it will be done. I was too tired of my week work to take the tools and make the wall stand for it, but I'll do.
For microphone, I'll definitly use a head set so I can manipulate the game and the PC with my two hands
for the live broadcasting, I almost did it with VLC +justin TV. The streaming quality is great offline really close from direct input...Now I have to figure out how to send the streaming to justin tv server
for the passing simulation, I'm using a fiberboard gameboard so it's not a magnet...Or to be more specific, yes it's a magnet, but I added some tacky putty on it (called patafix in france). That passing ball marker gave me great help in the past, but I'm modelling a new one, with scale ball and larger base for it, because it's really

when you miss it for 0.5centimeters...I believe I'll use a s something a bit bigger like a coin (20mm or 25mm).
With that current setup I'm already pretty close from real college/pro football passing completion rate. On the video, it's also a good exemple that passing simulation is not so easy, and not slow to setup. You can see on the video (even if there is some montage) that using the ball marker and passing simulation is as fast as using a TTQB.
Just a matter of choice.
