Absolutely could be done, In fact it was. back in the early days of DVD-A the Demo Kiosks at Circuit City and Best Buy were exactly what you are proposing. I tried to find a picture of one but could not. you would walk up to one of these and kind of step inside the area and it had a screen in front of you with a little sub and center speaker below and off to the side attached to some posts were some small L and R speakers, and then a post went over your head with like a T bar attaching two surround speakers just behind you and to the side about 2'. it was made for 1 or 2 peeps to stand in the area at a time. I think it was all those little Bose speakers. It sounded pretty damn good and in fact it got me hooked on surround again, It had 6 or 8 discs preloaded, and it was so cool I had to listen to every one. I will never forget because I discovered it shopping with my old lady and she got so pissed off she left me there and came back a couple of hours later.
