I'm the author of Blogofile (http://www.blogofile.com) and am creating a new plugin system that will allow people to install third party Python modules as plugins to Blogofile. There is a current discussion on this topic here:
The best suggestion for how to do this so far is to just use Python eggs for plugins, and we'd be able to leverage the existing functionality of easy_install or pip for versioning and dependency management. However, Blogofile plugins are not necessarily Python source code, they could just be CSS files for a Blogofile theme. The idea is to wrap this content in a Python module and retrieve this content via pkg_resources.
Would the inclusion of such modules, that have no actual Python code in them, but do enhance an existing Python tool on PyPI (blogofile) be an abuse of PyPI? Could a trove classifier be setup to indicate that these are Blogofile plugins?
