I maintained CMFBibAT for a while. My answer: forget it…the codebase is too old, too fragile…nothing worth being ported. A related functionality should be designed and rewritten from scratch with a focus on the functionality that is really need…CMFBibAT turned into an unmaintainable monster. Get in touch if you are interested in a fresh start.
The guys from Jazkarta had been working on bibliography solutions for Plone. The blueprint (from my memory) was that Zotero would be used for collecting and maintaining bib references. All data would be stored in the Zotero cloud. The integration into Plone happens through the Zotero cloud API (basically displaying references inside Plone, no management of bib entries inside Plone) - I hope I got this right.
