Yes, that is the right start, but you shouldn't require extensions to
create that "config" part. Instead provide some nice method in your
extension that returns the proper PHP-array to be included in the TCA.
See DAM and the "tca_media_field.php", function txdam_getMediaTCA. The
extension that needs to add a "DAM" field (or a category selector in
your case), simply does this:

	'images' => array(
         	'exclude' => 1,
                'label' => 'Images',
		'config' => txdam_getMediaTCA('image_config', 'images'),
	),

That has the advantage that you will be able to update the "TCA" part of
all foreign extensions that are using your categorization library
without any developer having to modify their code. They should just
stick to the API, which will be enhanced as TYPO3 core also enhances
(e.g. someday core might provide nice tree-selectors as TCA fields).
