Thanks, Brent. As I write up the docs, I am thinking about adding one more thing, which I would apprecate feedback on. I mentioned above that the RandomGenerator / AbstractRandomGenerator provided a generic facility for replacing java.util.random. Recompilation is still required, however, to use this. I am thinking now that it might be useful to add a class that *extends* java.util.Random to wrap a RandomGenerator to make it possible to do this in a binary compatible way. Does this make sense?
