While that would be really cool, there are two factors working against you. 1) Space is limited and, 2) All stations should be the same setup as attendees tend to stop the line and want something specific. For example, at PAX South, we had 7 computers set up, with 3 running 1080p and 4 running Oculus Rift. People wanted to hold up the line so they could play on the Rift. They had an option at that point, which was to go to the back of the line, or to the next available computer (which was a 1080p, obviously). Here are a few pics from PAX South.

Our booth before opening where Media, other Exhibitors, Enforcers, and even us Ambassadors could play, assuming there was an open station!
Ali at the head of the line, directing players to the next available station.
And... the Line. It was roughly a 30 minute wait at this point as we were running people through on about 5 minute intervals.
I wrote up a thread on PAX South with these pics and more. Here's the link:
