I've just tried to use the ANNEX_HASH_ variables, example of my configuration

<pre>
    git config annex.tahoe-store-hook 'tahoe mkdir $ANNEX_HASH_1 && tahoe put $ANNEX_FILE tahoe:$ANNEX_HASH_1/$ANNEX_KEY'
    git config annex.tahoe-retrieve-hook 'tahoe get tahoe:$ANNEX_HASH_1/$ANNEX_KEY $ANNEX_FILE'
    git config annex.tahoe-remove-hook 'tahoe rm tahoe:$ANNEX_HASH_1/$ANNEX_KEY'
    git config annex.tahoe-checkpresent-hook 'tahoe ls tahoe:$ANNEX_HASH_1/$ANNEX_KEY 2>&1 || echo FAIL'
    git annex initremote library type=hook hooktype=tahoe encryption=none
    git annex describe 1d1bc312-7243-11e0-a9ce-5f10c0ce9b0a library
</pre>

It's seems to work quite well for me now, I did run across this when I tried to drop a file locally, leaving the file on my remote

<pre>
jtang@x00:/tmp/annex3 $ git annex drop .
drop frink.sh (checking library...) (unsafe) 
  Could only verify the existence of 0 out of 1 necessary copies
  Try making some of these repositories available:
  	1d1bc312-7243-11e0-a9ce-5f10c0ce9b0a  -- library
  (Use --force to override this check, or adjust annex.numcopies.)
failed
drop t/frink.jar (checking library...) (unsafe) 
  Could only verify the existence of 0 out of 1 necessary copies
  Try making some of these repositories available:
  	1d1bc312-7243-11e0-a9ce-5f10c0ce9b0a  -- library
  (Use --force to override this check, or adjust annex.numcopies.)
failed
git-annex: 2 failed
1|jtang@x00:/tmp/annex3 $ 
</pre>

I do know that the files exist in my library as I have just inserted them, it seemed to work when I didnt have the hashing, it appears that the checkpresent doesn't seem to pass the ANNEX_HASH_* variables (from the limited debugging I did)
