Zend Route and Infinite Categories

I'm building a Cms for an organization and url scheme is like this:

departmentName.site.edu/subDepartment/subDepartment/evenMoreSubDepartments/module/controller/action/*

I think i have to combine Zend_Controlle开发者_开发技巧r_Router_Route and Zend_Controller_Router_Route_Hostname but i don't know how.

If someone can help, i appreciate it.
