       Hey I'd love to help with the installer , I've done a 
few                                                    
installer/provisioning/mass-deployment type of tools in a hosting
environment , and I've made all the really good mistakes already,
so that will save some time. I am also off from work all week,
I'll see if I can bang out something that meets the binary upgrade specs.
