You could also save numbers to a file, every time you render the scene, 
generate a random seed value and write that to the file. That seed value 
would then be used next time the scene is rendered, and a new random 
seed value would be written to the file.
Or you could make the random seed value a function of the clock 
variable, and render an animation. I've used this technique to generate 
a bunch of different trees with different seed values with some tree 
macros I created...I put a text object in the scene so I could match 
each seed with it's result.
