WebDAV for user account

Hi all, hi John - I know you're going to answer anyway ;-)

does anyone have any idea how to set up WebDAV for a user account? I am looking for Interworx specific hints as literally every source I could find on the net talks about the apache user, var/www/html, creating a specifc vhost file just for webDAV and so on.
I can see that the necessesary modules are installed by default and that apache conf contains
<IfModule mod_dav_fs.c>
# Location of the WebDAV lock database.
DAVLockDB /var/lib/dav/lockdb
</IfModule>

But I can't figure out, how to share a folder within a user account via WebDAV. Ideally some folder like /chroot/home/useracct/webdav

Did anyone do this on Interworx and is willing to share his way?

Cheers guys

Michael
