Thank you for the response. Don't take this wrong way but it seems that
all that cpu power could be better used. I guess I don't completly
understand the RC5 project. The folding at home project can and has added
to medical and general technology advances. I would really like to a
see a distributed AI project however. Image a General AI that could be
trained on a network the size of the one that distributed.net has put
