Interesting new concept. As much as I hate ticketmaster, this isn't a bad idea. I've had to get to the poker room early before to register for tournaments. I've at times had to gain my seat off the waiting list.
On another note, I always wondered who invented that poker room queuing system that you see on the LCDs across every poker room. I figure that guy must be loaded at this point. Whenever I stare at the LCD waiting for my name to pop up on the waiting list... I ask myself why couldn't I have thought of this?
