How tall is the tallest possible building?

This morning I was in an elevator with a woman who was listening to her messages on speakerphone. Lucky for me, the ride was only a couple floors. I’m not sure I could’ve lasted if the elevator ride were, say, a mile long. Atlantic Cities Nate Berg asks the experts: Is there a limit to how tall buildings can get? (We already know there’s no limit to poor elevator etiquette.)
