Write some Software

I need a menu similar to the "ipod style menu - with breadcrumb" on this page ([login to view URL]). I want the menu to scroll down with each UL and have the breadcrumbs to jump back up levels like the demo. What I want different is SIZE. I need to be able to pass the code a desired font size, and everything else follows suit based on that size. I have a very limited set of users, and I can set their desired font size in the database.
