I suspect even if the repeaters will work with the light wavelength of "near IR" that latency could make it unusable. I mean we are talking about tiny fractions of a second here. But atforty bucks it might be worth trying as a proof of concept. I'm sure someone could make something that would do what I'm talking about but I don't want to invest much time, money or energyif the concept is flawed.


It's quite likely thatsomeone reading this owns an IR repeater (A devicefor making an IR TV remote control aSat/Cable boxin another room)a Canon master(ST-E2, 550EX, 580EX, or 580EX II)and slave(420EX, 430EX, 430EX II, 550EX, 580EX, or 580EX II)to test this. Anyone???
