Tom, having a source of "real" random data isn't useful just for crypto applications. No PRNG is perfect, when it comes to statistics.
The various proposals to create a more-secure, less-portable variant of random() don't seem appropriate to me for beta. But I'd not object to someone whipping up a contrib module for 8.1 or beyond.
Agreed.
