I just downloaded OOo 3.2 from the website to try that out, but didn't see the link. But what I did do was open a file directly from my Briefcase and save it back directly there. Which is really cool!
What I did was open the file using
https://[servername]/dav/[username_without_domain]/Briefcase/ and looked it up from there.
It's not the most comfortable of ways (having to type the full URL in) but it works.
