Very Good!
Perhaps one of the more illustrative examples.

If that wife is very entertaining and is faking playing by using midi files, is that OK.
I guess from the wife and husband�s perspective because she is getting the job done.
Just imagine in the future multiply that by the nth power where instead of arranger playing and persons actually playing an instrument, the way gigs would be done is by sitting or standing behind a computer manipulating tracks and sounds to �entertain� the audience. And what if that new trend causes you to either put up your arranger or musical instrument and join the computer manipulation crowd (playing less music) or don�t play at all. At what point do you draw the line?

I think as part of the nature of humans ,we only want to be fair and moral when we are getting the short end of the stick. Or when the shoe is on the other foot. We saw this in the sampling issue.
