This is incorrect.  What Otto asked for is called namespace packages and 
its status is a bit complicated.

- If you use only the standard library, then 
http://docs.python.org/library/pkgutil#pkgutil.extend_path can be used. 
  On the packaging side, you can use distutils to package your two 
projects and the second installed will overwrite __init__.py, which is 
okay given that the contents will be the same.

- Most people use the flavor of namespace packages provided by 
setuptools.  (setuptools is a set of extensions to distutils which 
people tend to love or hate.)  I don’t remember how it differs from the 
pkgutil flavor, but the docs for setuptools and distribute (a setuptools 
fork) should explain it.

- There is an ongoing discussion to add better namespace packages in 
Python 3.3.  When it’s done, packaging/distutils2 will add support for it.

Cheers
