Some are not that expensive (10£), and maybe they can do good “dbeam like” sensors ?
Do you think they worth the try ?
tell me it doesn t create sub harmonics at 20, 10 Khz etc and i ll buy one!

What is this ???
This item looks cool too http://www.robot-electronics.co.uk/shop/Serial_Interface2110.htm
tell me it won t interfere with audio (as audible) signal and i ll buy one, this guys use to emit slightly audible frequencies, thus useless if you are using instruments

aah, ok, sorry it was unclear to me…
so, i dont know yet if they ‘sound’, but, for a live performance, unless if you are using microphones of course,
it should not be a problem !
