Hi,
our plan with the bibliography collection of GNUnet is to implement something similar to your/freehaven's anonbib.
While running the build and cache update of it from current git HEAD on the anonbib.cfg I noticed a number of outdated and broken links.
I'm currently playing with 2 options: re-use anonbib as it is and change the style + some of its content (for us at GNUnet) or write something similar to it. From my perspective option 1 would be the best as we could work on fixing links together, keep the content up-to-date and at the same time keep the duplicate efforts and work down to a minimum.
What do you think?
