So there would be a configuration file for each application that needs
it?  I like this a lot more then the global entry-point registry too
(it avoids name collisions for entry points too).

But how can a "python setup.py install" know where to find this
configuration file to add it's plugin?  Or should this be an explicit
manual step?  It might be nice to have a --register-plugins option to
the install command though if possible.  Something else to keep into
account is the FHS, I can imagine GNU/Linux distributions would want
to place a configuration file somewhere else, like in
/etc/PROJECT.conf instead of
/usr/lib/pythonX.Y/site-packages/PROJECT.egg-info/plugin_registry
(pathnames are fairly random examples).  The only thing I can think of
is somehow having a file in .egg-info telling you where the plugin
configuration file is, just like was proposed for all types of data
files earlier on this list.  But I think by now I'm taking this too
far and the install command of distutils should not be able to
register plugins for random projects automatically.
