>I will close with something to consider... would you call a building contractor and tell them that you want a house built - without any architectural plans? Do you think they would build you one (prototype) to see if you like it for free? If they had a great crew and had done this a thousand times before - would you be willing to allow them to work quickly (RAD) - without actually having any idea of when they would be finished or how much it would cost?

Watch "Trading Places" sometime ... that's my point.
