ConnectorServlet: indirect file system mappings

I'm just wondering if the ConnectorServlet of FckEditor.java is able to support mapping to a 'virtual' file system.

In otherwords - the view that I want to present to the use in the browser is not necessarily exactly the same as the way the files are stored in the underlying file system. Is this possible?

For example:

Let's say we have a system that 'logically' stores images in a gallery under different categories. We want the user of the server browser to see the images organized into separate 'folders' that represent the categories. However the DB is responsible for storing the images and it allocates a unique ID to each image and stores them ALL in a single 'images' directory on the 'physical' file system. Is this kind of thing possible via the ConnectorServlet?
