Open source spaceship

Virgin Galactic revealed plans for SpaceShipTwo with an open architecture today. From the press that I read, it looks like Virgin Galactic will be more of a user of open source than an open source company. Still, the words "open source" next to the word "spaceship" is pretty cool Yes, I think the open source model has evolved. If it is good enough for rocket science, it is surely good enough for data networks!
