Has anyone written/converted a pseudo-random number generator that IS
cryptographically strong?

Have you looked at LavaRnd?

I think it would be awesome to get a Ruby adapter to the LavaRnd system.

I have a pure-Ruby implementation of Fortuna (the crypto-PRNG
introduced in Schneier’s “Practical Cryptography” book)
in my crypto lib. I’m reluctant to release it though until
I’ve fully understood the restrictions on exporting crypto
alg’s from Sweden. I hope I can get this fixed RSN.

Here’s a pair of classes that use www.random.org and
www.fourmilab.ch/hotbits -
