I was thinking you can send a master clock signal (eg. I was wondering if it was possible to use the IEEE 1588-2008 standard (Precision time protocol over ethernet) to get similar accuracies - even up to about 20ms accuracy would be OK over a standard WiFi connection? But then of course you have all the latencies etc. However having to wire up all the buzzers (up to 13) each time was becoming a pain and it doesn't scale very well, so I was looking at using tablets (probably Android based) to transmit over WiFi a virtual buzzer press. I used a USB-6001 DAQ unit for a Quiz Buzzer game that worked down to an accuracy of 1ms - great no problems.
