I tried https://github.com/google/git-appraise-web, with a review made only locally, not pushed to the remote, but it doesn't seem to work. Did I miss something? I went up to accepting the request, so the command line is working, but the web GUI - at each step - only shows a closed request [0], and clicking on it gives an empty page.
there is a web interface [1] and also an eclipse plugin [2]. It would be nice if there was an intellijplugin as well.

It's not fossil-scm, but git-appraise restores some of the lost distributed'ness:
https://github.com/google/git-appraise
https://github.com/google/git-appraise-web

And there's also http://jk.ozlabs.org/projects/patchwork/ (http://patchwork.ozlabs.org/project/qemu-devel/list/).
