As you said, it looks like you're really overengineering your design then.

That may be an option.
You may want to setup a simple registry mechanism, so the plugin modules
look like:
### begin niceplugin.py ###
class AVeryNicePlugin(object): # or perhaps using a suitable base class
def handle_message(self, message):
...
from plugin import PluginRegistry
PluginRegistry.register(AVeryNicePlugin)
### end niceplugin.py ###
Your application scans a known directory for files ending in "plugin.py"
and imports them; the modules register themselves any class (or classes),
and at appropiate times the application calls some method(s) of the
registered plugins.

Why not? Get another free account, post using a pseudonym, and nobody will
know that *YOU* were the guy that asked the most stupid question of the
week :)
