XUL Base

As you might know, with XUL you can read local drives. This is part of the built in interfaces you can access with JavaScript and soon Python.

What makes it even more interesting is that you can get this information in RDF form and apply it to virtually any DOM element in your XUL interface.

There is a good tutorial about RDF datasources on the Mozilla Developer network.

This means you can dynamicallly create Menus, trees, grids etc. based on this datasource. Even if you have a drive connected through USB, XUL takes care of refreshing your gui.
