As a musician, and reasonably familiar wi tech .... I can tell yiz ... it IS possible tae create a system whereby, even in an empty ground, that viewers can pay to watch a 'televised' game .... and opt for their PC/lappie mic to be active .... and all fed into a sound system at the 'fanless' match venue so that all us folks watching on screen can contribute to the atmosphere ... and if done properly, our audible 'yaaasss!' would happen in real time ... !

.... it's all very possible ... and the idea would encourage subscription. It would be costly to set up, but arguably more costly NOT to ... so it's all about will. ... or will it not??
