Sure. I'm struggling to understand what utility your questioning. Is is it the fact that they are using a hardware based random generator or the way in which they are using a hardware generator (e.g. lava lamps)? If the former - my question would be - surely you, as a security expert, would agree that a hardware random generator is more secure than a software based one (PseudoRandomNumberGenerator or DeterministicRandomBitGenerator)? If the latter - why does the way in which they use a hardware generator matter as long as it provides some utility and advantage over a software-based one which has a deterministic set of numbers?
