Great idea. I did have a look at conference algorithm. It's first added up
all mic
voice wave and than minus listener's voice from it. By this mean, we could
also
increase volume of voice of whom looked at listener and added up before
sent the wav to listeners.

However, the difficult part is how to figure out if someone is looked at
someone?

Can't answer that, just motivate it as a more generally useful idea.
