I do not know. All of the conferences I have seen, unless they are way-out-there conspiracy minded conference don't say anything real.
Eric Dollard doesn't really say anything real... mostly because he talks to the audience in general theories. Speaking at any depth is difficult because "science" has brainwashed all the science minded people. They have to be deprogrammed before you can even talk about definitions.
Also, specifically what I am propounding is 50 year old technology. I get most of my information from books and papers written in the 70s, or earlier. So, they are not very great for drawing a crowd.
