Adam,

You might want to wait until Dick finishes his DLL work.  At that point,
the UI code should be separated from the core Pcbnew code.  Then it
should be fairly easy to create command line tool for plotting (or any
thing else for that matter) purposes rather than go through wxApp() and
not show the main window.  It might even make more sense to use python
scripting to complete this task.
