I have to say that I'm in a similar situation to Red. I've only been brewing for a couple of years and I don't think I can justify admission for two, plus cross-country airfare, lodging, food, etc. I seriously considered it and I may attend in a year or two, but right now, I have a hard time swallowing the total cost.
If a virtual option were available, I'd certainly look into it.
I also wanted to comment on "Has home brewing become a "mature" (in terms of content) hobby?"
My wife makes sausage, and I've always found it interesting how there really aren't many new innovations in that space, while brewing has been evolving fairly quickly for a while. My guess is that (a) homebrewing wasn't legal until relatively recently, and (b) I don't think commercial sausage making is at the same scale as commercial brewing. I think there were new markets that opened for brewing gadgets and there's probably tons more research into brewing.
It just struck me as odd that two ancient practices are so different today: one still evolving while the other is basically stagnant.
