Making DAM categories choosable in Flexform:

<damCat>
    <TCEforms>
        <exclude>1</exclude>
        <label>DAM Cat</label>
        <config>
            <type>select</type>
            <form_type>user</form_type>
            <userFunc>EXT:dam/lib/class.tx_dam_tcefunc.php:tx_dam_tceFunc->getSingleField_selectTree</userFunc>
            <treeViewBrowseable>1</treeViewBrowseable>
            <treeViewClass>EXT:dam/components/class.tx_dam_selectionCategory.php:tx_dam_selectionCategory</treeViewClass>
            <foreign_table>tx_dam_cat</foreign_table>
            <size>6</size>
            <autoSizeMax>20</autoSizeMax>
            <minitems>0</minitems>
            <maxitems>2</maxitems>
            <default></default>
        </config>
    </TCEforms>
</damCat>

And than a overwrite function is needed - e.g. in listview:

$startpath = $this->div->validatePicturePath($this->piVars['category'] ? $this->div->hash2folder($this->piVars['category'], $this->conf['main.']['path']) : $this->conf['main.']['path']);
$pictures = $this->div->getFiles($this->conf, $startpath, $this->conf[$this->mode . '.']['order'], $this->conf[$this->mode . '.']['limit']);

$pictures = $this->div->newOverwriteFunction4DAMcategories($this); // overwrite pics with pics from category

This is just a first hint...
