Fair enough, clearly there is far more that could be done than we want to do in the first stage. Right now I am in the mode of listing all the stuff and then trying to pick off waht is easy, what is hard, what we don't want to do intiall but we need to consider in the design so we don't paint ourselvers into a corner.
