After reading a bit about it, it seems very difficult (impossible?) to get a true random set of numbers. Anyboyd here on HN that has some insight? Are there interesting hardware or random-number-as-a-service things going on?

Some of them are not very good. Here's an old (2000) look at some hardware rngs and how they fail: http://www.robertnz.net/true_rng.html
