you are absolutely right and thanks for the answer!

everything was already possible several 'days ago'. also in my opinion 
fm is one of the most reliable and realtime solutions. same with 
infrared assisted listening systems - in several situations (eg. 
theaters) this is still 'state of the art' (best latency performance and 
good area-coverage!) though the technology is really *old. all main 
players still have ir systems in their product range. crazy... isn't it?

we thought about that. doubts: in public spaces this might cause a 
higher probability of 'listener-clouds' in the area of the loudspeakers 
which should be avoided. this might happen anyway in a performance 
situation but we want to reduce the probability with the system-design.

but yes, a higher number of distributed loudspeakers is an option. side 
effect is a higher number of people/time to physically set up (and down) 
the [fix scale] system. hmm, maybe still cheaper than a digital solution...

no upsides without downsides. let's see what happens in the end.
