I have a custom content management system a friend and I developed that needs to be made more scalable. Ie., I need to make it so that I can rapidly deploy it to other clients. This involves creating an install script, incorporating a template manager (it's already using Smarty but needs an admin-side template manager ala Wordpress), clean URLs via mod rewrite, and making the different data-types into more flexible objects (ie., the ability to easily structure the site on the fly).
