Strength And Honour is planning on having representatives attend. Yours truly will be the first to confirm at this point, with others to follow.
I have a couple InFocus XGA digital projection systems for presentations, movies, games, etc. that I can loan to the organizers. Perhaps some black lights and fog machines as well.
My guess, especially after PSUMA, is that you may need to expand your maximum number a bit. With this much lead time (one year, right?), you'll quickly fill 40 well in advance, perhaps doubling that number. At least that's what my crystal ball tells me.
