I'll get in touch with Lenny's Subs and see what they would charge to deliver a large party sub or two. I'm sure we could all chip in for something like that.
I agree with Newlin though; it's very easy to get caught up in the fun and forget to eat! That's why I'd like to have breaks in the presentation schedule. Sure, many of us will still want to stay at the auditorium to tinker with stuff, but at least we'll know that it's time to eat... (And there are several options for food delivery if folks don't want to leave.)
