I'm looking for the mercurial+bazaar equivalent of hg-git. I intend to use this for occasional cooperation to avoid learning the quirks and tricks surrounding YAVCS: I'd prefer to do use one client for as many operations as possible and thus avoid the time investment for a tool not directly useful to me.
Well you do get bzr-hg (https://launchpad.net/bzr-hg) but its not complete yet. You also get bzr-svn and bzr-git, so I'm using bazaar as my one tool to access them all, but it does not always work perfectly yet.
