In the late 90s I was part of a group that built a online casino for folks who ran a sports book in the Carribean. Due to legal woes which meant they could not land a license in their Island domicile, they ended up not launching it.

He insisted that we spend an inordinate amount of time ensuring that the seed to the PRNG was as random as possible. The second thing was using PRNG's that had a long period and other desirable qualities but I think it would be vulnerable to hacking in this manner.
