For some reason, OmniFocus just isn't finishing its WebDAV syncs. I tried copying a disk-synced file to a WebDAV server, and the iPhone app sees the database, but no data shows up.

Yes, this is exactly what I'm seeing. I don't have any control over the WebDAV server, so I can't rule out it being a problem on that end; but since OF isn't giving any errors, I would guess the problem lies with OF.
