Bita, have you tried using PROPFIND to compare  the value of properties if
it's specific resources you're interested in?  You may have to do two
requests, of course.

Search is similar to PROPFIND in the scope of resources that it can handle
in one request.  None of the WebDAV methods take a list of resources to
apply to.
