It seems like it will work well if you know you have a situation that fits well with the setup. Do you spend 4+ hours out of the house and this is in a large, rectangular room with no one walking through? Perfect.

Two people have mentioned garden applications, so maybe back yard and outside applications are where the creator needs to explore.

Though, I agree that my spouse would rather burn the house down than set this up in the living room where cables would be "ugly" and not match with our decor.
