These kinds of events are usually much like the fun fair. A bunch of booths, bright lights, and gimmicky gadgets. Everyone trying to yell louder than the person next to him, and each business bragging about their latest technology. This is undignified and not really B&O's style, I think.
I attend the AES (Audio Engineering Society) conventions when I can, and while the conference parts are usually enlightening and inspiring, I find the exhibitor floors to be tacky. Maybe I missed it, but I didn't see a B&O booth on the exhibitor's floor of the last year's convention (in San Francisco, '06). However, B&O was represented at the convention--they sent one of their "Tonmeisters" to present a paper. (I believe it was about room acoustics, but I can't remember exactly, to be honest. I remember being very impressed.) That's more B&O style. Leave flashy /empty marketing to other businesses.
