Has anyone gotten OneNote 2007 to Sync with a non-IIS WebDAV server?

Using the rest of Office 2007 I can read and write to my WebDAV folder
just fine, but when I try to create a OneNote 2007 shared notebook on
the same WebDAV folder, it creates the initial notebook, but then
refuses to upload any actual content I put into the notebook. It gives
a 005 error when I manually sync.

I filed a bug on the Microsoft OneNote Connect site, but the ticket was
resolved today with absolutely no explanation.

So, 1. is anyone successfuly using WebDAV with OneNote 2007? And, 2.
Microsoft, what's the status with this bug? Is there a work-around?
Syncing across the Internet is a 'killer feature' for OneNote, and you
have it 50% working (creating the proper folders)... why not get it to
100%?

Thanks.
