Hi Greg, I missed that original blog post of yours but that is indeed exactly what we are trying to evolve so as to get an initial working draft out of PSB (or at least the structural outlines of such a thing). As deepak says in the comments to your post we will need to be very careful about minimum standards - further blog post on this will be forthcoming as soon as I can get myself back into the right timezone (probably just about in time for me to got to Waterloo!)
