I'm a bit disappointed that they didn't get any science out of this. If you're going to send cheese to space, you should hire some food writers to eat it, compare it to non-space cheese, see if there were any salutary effects, etc.
For those, like me, who don’t get it: <a href="http://www.youtube.com/watch?v=B3KBuQHHKx0" rel="nofollow">http://www.youtube.com/watch?v=B3KBuQHHKx0</a> (I still don’t <i>really</i> get it, though.)
It's not just ballast, or ebay fodder. I see two symbolic meanings of the cheese related to SpaceX's asprirations:
Cheese is food, which symbolizes the ISS resupply mission. And the cheese wheel symbolizes the moon, where they also want to go.
Just imagine if they had to do an emergency abort and blowup the capsule in midflight.<p>There would be a mysterious burning cheese smell across the country :D
