Just use any decent PRNG (that's pseudo-random number generator -- but don't let the name fool you) to calculate the random byte stream simultaneously with the blu-ray stream. The PRNG could output much faster than current optical disk I/O. Do PRNG's work? Don't ask a scientist. Don't ask a mathematician. Rather ask a gambler. The huge gambling industry, involving TRILLIONS of dollars annually, relies entirely on PRNGs -- and those bloodsuckers and money grubbers aren't going to deploy a faulty technology with that much cash at stake.
