That wasn't a good answer, you already discovered that.

But, you may want to organize your plugins somewhat differently.
Maybe you can create a plugin package (a directory plugin, which
contains an __init__.py file).  And then you (or your users) write the
plugins as modules contained in this directory. Or someting like that.

It may be useful to look into sources which do something like this, PIL
comes to mind, but there are most certainly more.
