Could this be the beginning? This is exactly the type of commercialization that will lead to large scale space exploration. This plan looks a bit shaky but if successful could create a fuel infrastructure in space, gas stations for spacecraft. Not only that but simply having a successful "fleet" of craft in space should be enough proof of concept to convince other companies to take the plunge. Especially if they get those 3D printers they're talking about to make the craft out of rock goo, self sufficient mining replicators...where's my shotgun...
