Two options you should consider:
1) The Twisted framework has a very nice plugin-architecture you
can use, whether you use the rest of Twisted or not. Google
for "twisted IPlugin".
For an example, you can take a peek at the Dallas-Ft. Worth
Pythoneers' subversion repository - we played with it a bit,
in relation to providing plugins to the D-BUS architecture.
2) Python eggs, using the Setuptools software, have a concept of
entrypoints, which are named and categorized. They are an
upcoming standard way of doing plugins for Python. There is
a standard API for querying for entrypoints.
You can read all about it at:
It is also the method used by zc.buildout, a great
tool for managing development/deployment for repeatability.
And then the third way, of leveraging the interfaces database of the Zope
component system, as described in the article you provided.
