If you are going to include the non-recurring costs of Falcon/Dragon
in the per-ton figures, you need also to include the non-recurring
costs of Shuttle.

http://www.spacex.com/falcon9.php suggests their contract with NASA
was for a minimum of 12 flights. (And claims 1.6 billion). With an
option to order additional flights to 3.1 billion.
