How did you know that I would jump in here????
I think that it could be cool, but to get the effect right, I would think that you would need some pretty decent height to your ceiling.
Plus it isn't a "game changer" in audio considering how much you would need to spend to get it to a distinctly higher level.
I mean 7.1 was out for a long time before it became "the" thing to do and media started having discrete 7.1 audio, since then we have 9.1, 11.1, etc and there is no media for it. All just "matrixed" type of technology brought up to the 21st century. Until you get more discrete channels on media, I don't see it as being anything more than taking a second set of rear surround and a second set of side surrounds and putting them on the ceiling.
