Yes, and in the present.

zope.interface as well as the other ZODB dependencies are distributed  
separately.  You don't need Zope.
I guess I need to make the dependencies easier to discover.  They are  
listed in the readme file, but I suppose that isn't something one is  
likely to read when using a windows installer.  I should at least  
make this much clearer on the PyPI page.

The easiest way to install ZODB (and most other packages) is with  
easy_install (or other setuptools-based tools), as this will  
automatically download dependencies.  In fact, I'm tempted to stop  
making windows installers and make the ZODB3 egg the only binary  
release.
