Comment (by dawuud):

 The design doc states:

     2d. If any of the following are true, then classify as a conflict:

     - there are pending notifications of changes to foo;
     - the last-uploaded statinfo is either absent, or different from the
 current statinfo;
     - either last_downloaded_uri or last_uploaded_uri (or both) are
 absent, or they are different.


 I've attempted to provide basic remote conflict detection by comparison of
 ancestor URIs as described in the last point of section 2d.

 Here's my dev branch:
