Return to the moon

Yesterday I got a chance to read the text of Bush's speech at NASA. It feels to me like he is inspired by the moon colony in 2001: A Space Odyssey. I can't imagine there is the political will to increase the NASA budget. And I wonder if there is even a conceptual design for a new vehicle to go to the moon. Much less a cost estimate--Bush wants to spend 11 billion over 5 years but that covers only the period before any construction starts. What is the connection to his father's proposal?
