Blogroll import/export with categories and descriptions

Question

Is there an easy way (a plugin maybe?) to export and then import into a different WordPress installation all links in the blogroll including descriptions and categories?

I know you can export links by going to /wp-links-opml.php, but I believe doing it this way you loose the link descriptions. When importing, I'd like links to be put in their categories - if the categore does not exist it should be created.

I would prefer a way to do this without hacking any core WordPress files if at all possible.
