I like this model. It makes a lot more sense to get people used to the technology without a huge upfront investment. The biggest reason that I don't have a 3d printer is after the first week of making things, I have no idea what I would possibly use it for. Having a setup like this would be perfect as parts would still be rapid (compared to having them made & shipped) and it would save the large upfront expense. Sure there may be some quality & operational issues to address, but that's fine. A webcam might be useful for both the end user to watch his part being created and for the operator to remotely check for jams, clogs, messes, and other disasters.
