Use the animation feature.

You can use frame_mumber to seed your random stream :

#declare R= seed(frame_number);

You also can  use the clock variable :

#declare R= seed(clock*1000);

In both cases, you can add some constant. You can combine both :

#declare R= seed(frame_number*2+12 + clock*100+3);

Use rand(R) in your scene.

Then, place +kff100 on the command line.
For the Windows version, the command line is the text box just to the 
right from the resolution selector.
Hit the Run button and you'll get 100 uniquely numbered images. The 
number is frame_number.
