Hmm. I still use darcs + ssh directly. 

At least for the case of 'darcs pull' (or is it push?), where darcs
seems to ask for several passwords for each patch (or several DSA key
checks), the master/slave trick seems to help. 

For the 'darcs get' case it probably does make more sense to use http to
grab the source. But perhaps we should check with David and the darcs
crew for any known inefficiencies in the ssh method?
