Multiple custom write panels for a single post type

Whether for "posts", "pages", or custom post types, there's a "write panel", where you can have certain meta boxes to fill in custom fields and more options.

I want to have a "simple" and "advanced" (or some other variation) version of a write panel for a custom post type of "listing", for example.

I'm not sure if I want it for usability (give any author the option to use the write panel they prefer) or for security (only Editors can change to Advanced while Authors don't see that option), but I do want to either have a plugin or have the coding to do it.

Is this a plugin or a theme question? Any answers for me?
