Hard to tell, but sounds good I would say :-)

Note that a readonly tar translator already exists IIRC, probably in

Indeed, something along the lines is certainly useful to learn about
translator programming in general :-)

In view of the task you want to work on, it might be even better though
to write something directly involving namespace manipulation: For
example a translator that reads a list of file names from the underlying
node, and creates a virtual directory mirroring the listed files.

Or a translator that filters the underlying diretory tree, showing only
those files that give a "true" result with the specified filter
expression (which can be an arbitrary command to execute).

What do you think, do these sound interesting? :-)
