I wrote: If a folder doesn't itself contain a required object or method, I'd like to have another folder looked in instead. The fall-back folder won't necessarily (and often can't) be higher in the hierarchy, so acquisition doesn't seem to be a solution. Steve Alexander wrote: Your requirements sound very much like those for Shane Hathaway's Transparent Folders product, except that instead of briefly diverting acquisition into the transparent folder, you want to briefly divert acquisition into some other arbitrary folder. Steve, thank you very much for that information. I eagerly await the re-release of Transparent Folders.
If you don't have sufficient python-hacking-zope-hacking-Zen to do it yourself, I think I might have a go (and hopefully learn some Zope internals Zen in the process).
Though I have a reasonable amount of Python experience, I'm just starting on Zope development. Depending on how I get on, I may take you up on your offer!
