Now, it's certainly a good idea, but how are they going to do it? While the Soveit Union completed three lunar sample return missions back in the early seventies as part of the Luna Programme, one must agree that it is extremely difficult.
To collect samples on the Moon, launch a rocket back to Earth, re-enter the atmosphere and survive the landing. Even the Google Lunar X PRIZE mission to land on the Moon and drive a rover around is already far more challengining than anything achieved by privately funded space companies.
Good luck Interorbital but we suggest you don't offer a service guarantee ;)
