The spacecraft took 1,000 pounds of food and supplies to the ISS and will bring back some of its trash and garbage in the reusable return capsule.
If I were a NASA bureaucrat, I'd sure be looking for a way to hobble those Dragon guys with a boatload of regulations, rules and requirements insuring that NASA would keep it's finger in the pie. After all - NASA has just about written itself out of the manned space business by shutting down the Shuttle fleet and canceling its expensive - but dated - replacement.
One thing about the Dragon capsule and it's launch system... It wasn't built by the lowest bidder, so we probably won't see a repeat of the Apollo 1 disaster when future Dragons take astronauts into space.
