Due the fact that I work from home, I took myself out of consideration for promotion, but in my company you start in the lower position and then do the work that the manager would do. Onec you prove you can do it they typically promote you.
Really though it depends on your boss's management style and what her or she looks for.
Also although you may not have Managment as a title, have you actually done any work that would fall under that category? Such as training new hires or being responsible / supervising other people? That counts as experience...
Good luck!
UPDATE: Not with it this evening - have you looked into volunteering? I am not sure what your area of expertise is, but that is a good way to gain experience and help a good cause..
