Is there any progress on a the plugin/feature? I like the idea of a nice duplicate detection feature in calibre. So far a lot of people are doing there own duplicate detection, maybe together we get a nice and working solution.
Has someone started anything yet? I have never done anything in python so far I did everything in java and ruby but maybe I can help with python as well

If someone has started it would be great to be pointed to the general stuff that is decided the sourcecode repository and everything else useful. I would like to look at the stuff, learn and try to help.
