I agree.  I've used similar randomization techniques for software testing, 
having similar requirements for repeatability.  (E.g., finding a seed that 
generates an error after several million iterations, with a specific 
iteration number, and then re-running the test to enable tracing at exactly 
the required iteration number.)
