I'm not really sure if there is a detectable bias, I'll try and test it over the weekend when a friend comes round, I don't think i can reliably test it by myself.

If I have a problem with bias, I think I will take your idea of polling the pins up front and measure which teams buzz in in each loop, but then pick the 'winner' at random. Or, at 'random'.

edit: I just had a go at 60 simultaneous button presses of adjacent buttons and it came up as 28/32 which i think is pretty good.

An update:

I had caps printed for the buttons at shapeways.

Looks sharp. Do they use a mold to give it the crisp shape and build up the plastic with 3D printing kind of thing?
