And PyWin32's installer is the result of a bdist_wininst? I didn't know the
pywin32 installer was created using bdist_wininst, and I didn't know that
bdist_wininst creates a zipfile. Is this what makes you guess I don't have a
clue about how distutils works in general?
Anyway, that's good news.

We're just talking about Zope here, and installing Zope into its own
buildout (possibly sharing eggs with another). This means we don't care much
about installing the documentation anyway, just having the libraries
importable so that Zope can do its work on windows.
Of course it's possible just having the dlls on the path might not be good
enough - perhaps some (say) registry manipulation is needed in order to make
them work properly. Do you know whether such might be the case?
You're giving me the impression here that it might be less than extremely
hard to eggify pywin32 for our particular use cases.
Anyway, even if it turns out too hard to get an egg going, the zipfile-ish
nature of the installer gives me hope that we can at least write a custom
recipe that installs the dlls into a part. Of course we'd need some logic
that manipulated the environment in buildout-generated scrips so that these
dlls can be accessed from them..
