Good question, Chris!
I've been quite busy developing a line of prosound speakers, and so hadn't planned on attending RMAF this year. Then this invitation was extended, and participating in the seminar is several orders of magnitude less daunting than doing an exhibit room (at least this go-round) so that put it within the realm of possibility. And besides, it sounds like a helluva lot of fun.
Tony Knight sent me some actual in-room measurements, and they are unbelievable. Like plus or minus 1 dB from below 10 Hz to about 16 kHz. He uses multiple Quads and custom subwoofers in a purpose-built room, he doesn't skimp on room treatment, and I'm sure he's going to teach me a thing or two about DSP correction. Unfortunately we won't be able to replicate anything like that for the presentation, but he has a most interesting demonstration planned (described in the link in my first post).
