Yeah, I'm feeling a little lost in the weeds. Taking away inheritance looks like it will necessitate implementing a lot of hacks and ugliness in the code to get to work properly. I was hoping to make it dead simple to implement a plug-in. My module works well, as is, with the parent-child inheritances hard coded in to the classes. I'll keep toying with it and see what I can come up with. At a minimum, I'll at least learn a lot.
