All of the tech conferences I use to work when I was in media had "behind closed doors" areas in their booths, which were basicly office like meeting rooms. Some of those they showed us stuff that was not on the show floor it self and were future products they were not ready to talk about yet. But the others were meeting rooms where people would come in and have meetings all day long. These were pre-arranged meetings. That is where the business gets done. The trade shows I went to though were far bigger than this so I am not sure how these booths would be set up. But Ken has private "behind closed door" meetings outside of the conference it self. I think it's pretty safe to say that both Vale and Anaconda will be two of them. While he might talk with some other people at the show it self, I wouldn't expect a whole lot to come from that.
Whats most important, and most interesting is there are a unnamed number of companies that are serious and really want to talk to, and possibly do business with Ken. That is whats important and most exciting. You litterally have companies seaking him out based on the numbers coming from his properties. Very very impressive. Any deals that might take place would almost surely happen between these companies and not ones he finds and meets at the show it self.
In anycase, more is better and the more he gets KATX out there the better!
