Suggestions for making "Addons" for a CI app?

Have a look at my alternative for Modular Separation: http://ellislab.com/forums/viewthread/164350/.

A lot less intrusive, supports both routing to module controllers (the modular separation way, but using simple route definitions) and calling module controllers from other controllers.
Supports all CI file types (controllers, libraries, models and views) in a module by using

Code:

// initialize our module
$this->load->module('modulename');

// call a module controller method
$this->modulename->controller->method();
