Seems a bit like a quick hack no ??

These two solutions seem cool, i'll try them.
but I've found this function by browsing in the source the
ZopeTutorialProduct :

import App.Common

App.Common.package_home seems to return the home of the package  (duh !!)

Humm as you say this is less robust. So I won't even try it.
