After post, I noted that my observations were not all fully correct. 
I was concerned that my query was too erroneous for response.

Your notes help tremendously, thanks!

Yes it should, but it requires that the back-end store support
Content-range (partial PUT). The tests should skip with an appropriate
message if the store you test against doesn't have these features.

(edit_file won't work for you unless the back-end also supports DAV

An approach which should work is to run mogstored with an apache DAV
server. You can either use the --server=apache option or use
--server=none and run against an existing apache DAV setup. (You can get
away without running mogstored at all, but you have to play around with
usage tracking and fsck performance will be poor).

hope this helps,
