Importing/exporting DL categories

Another wishlist item, but it would be handy if you could import DL categories (when setting up a new DL) from something like a comma delimited text file. This would allow users to set up multiple DL instances (if required) and easily give them all the same DL categories. The DL would probably also need an option to export an existing category structure as a comma delimited text file as well. (The Kaivo Document Library Zope Product that we are still using for our own internal purposes has this facility).
