I'll admit that I haven't thought this ALL out, except for a couple possible issues*. I did search but couldn't find a previous discussion about this topic. If one exists, I apologize for not finding it.
How hard would it be to put a microphone at the camera's controls so that whoever is controlling the cams could do some 'limited' narration of certain events? I don't mean loud play-by-plays like some sports announcer, or disc jockey. Just a normal person who could chime in once in awhile with BRIEF and calm announcements. I do like the natural sounds, but would love the occasional, brief, calm and to-the-point comment from a cam operator.
For example: I occasionally log in late at night (Africa time) and sometimes it appears that the operator is frantically trying to find something. It makes me wonder what I missed.
I realize there are chat rooms, but that is often cluttered with non-relevent talk.
*A couple of possible problems:
Bandwidth (a.k.a. $$$)
If the cam op doesn't speak english, a lot of us would be out of luck
