You might think that they were different markets, but in 2013, they stated that the SpaceShipTwo was capable of launching 100 satellites daily. Seeing as they have yet to get the thing into space in the first place while others have launched satellites successfully and their competition is looking to get into manned craft themselves, things are not looking good for them. Similarly, the tech they're using (rubber and plastic based solid fuel rockets) doesn't seem to be very efficient compared to current technology. The Concorde flew at supersonic speeds because it was more efficient for it to do so, but modern aircraft don't because advances in the old designs caused them to become more efficient. It's certainly a neat idea, but I don't really see the technology they're using filtering down to casual aviation.
