The reasons I see to make these stand-alone boards are

  1) If the entropy sources are the seat belts, we don't want to build the  
     whole car before learning if they are any good or not

  2) Some people might prefer a stand-alone entropy source over the whole 
     cryptech thingy because

       - price
       - time of availability (now, rather than in 12+ months)
       - simplicity


What I hope to get from a set of 10 units are

  - some seat belt testing
  - SPI interface design help/feedback
  - project awareness / publicity
  - validate hardware design before making 100 more (those would not be hand 
    soldered)


I also want us to set a new standard for the quality of the open source 
hardware RNG designs that are floating around out there. Benedikts Arrgh 
project also achieves this, but two implementations are better than one.

You said you didn't do shiny toys ;)
