Just to get an idea how this can be done using bash scripting if your wpkg share is on linux using samba, here is my script which checks if there is a newer version of google chrome. Only then it copies the msi file and creates new xml file from template. It substitutes the __VERSION__ and __MSIKEY__ strings, which are extracted from the msi file. Seems like a quick hack to get the strings out of the MSI file, at least it works at the moment.
