And _this_ sounds like a combination of something that's more
a design issue (the structure) and a trivial implementation
detail (trivial in Python, anyway).

I'll try anyway, as a first test case:  put all plugins in a
standard folder, with nothing else present in that folder.
They can be individual modules or packages as you will.
The code to load the plugin consists of an __import__...
and not much else.

Maybe this feedback will help you refine the question further...
