You are doing something wrong, either with the streams or with the 
random numbers, or with your interpretation of the results. The rand() 
and seed() functions do operate as the documentation describes, and 
multiple streams work just fine. I often use multiple independent 
streams when using several randomly generated objects in a scene...you 
can change one to use a different seed, and get a different randomly 
generated object, without affecting the others. It's especially useful 
in plant generators where not all seeds produce a good looking result.
