This is how I chose to do it. Just walking a list of bundles and
discover the available classes [as plugins].

Is there not an other way to create a fast addon system?
A module or something like that

How fancy are your requirements? People have written numerous plugin
systems, from simple to use ones like CherryPy's tool system up to a
complex component architecture like zope.component.

I recommend against exec() and execfile(). It makes debugging and
testing harder and it has security concern, too.
