Would like to see this, too. Currently cloning the whole SVN repository fails (probably because be moved trunk/ some time ago as we needed to restart the project, so this was the easiest way to clean things up while keeping history). Only cloning trunk/ would be enough, but hgsubversion seems to not support this. Funny thing is: The clone itself seems to work, but the hg repository is empty afterwards. I think this is, because only trunk/tags/branches are cloned?
