Linux Showdown, Or What Do You Want to Know in Linux?

So, little_bird sent in some information about the upcoming LinuxWorldExpo in February, talking about the program but also a "Linux Showdown". It's a feature panel consisting of "leading commercial Linux providers" with questions being field from a panel of experts, the audience and one another about Linux. My question - what would you want to ask these folks? What's on your mind?

BTW, I've also been told that if you register for any conference package by December 4, you're in a drawing to win one of twenty-five autographed copies of the upcoming Jon Katz book, GEEK. How Two Lost Boys Rode the Internet Out of Idaho. But the book is dedicated to Rob and I, so I dunno... *grin*.
