Given it's CCC, a hobbyist hacker con, OpenPNP and especially those three things you mentioned seem perfect, I'm not sure why you'd think it makes the con look bad. I've heard this talk mentioned repeatedly as one of the coolest ones there, and I certainly enjoyed it myself.

It's not an industry seminar on how to start a board house, it's two guys explaining how they automated the basics of production on a low budget and with space constraints, etc.
