Note they claim: "QUANTIS has also been approved by national authorities and can be used for gaming applications." If I were implementing this for a casino, I'd do what other posters have already suggested and use at least two independent hardware sources for my random numbers and XOR them together. IMO Intel's on-chip RNG would probably be a good source to use, but only in conjunction with others.
