A usefull feature would be an "addressbook" export (vCard format ?) when card models contain contact data (maybe by selecting the projects where this export would be available). I'm thinking of doing it myself from outside Kantree (and opensourcing the code if someone else is interested) by connecting the API but if it might be simpler if available directly in Kantree.
Or even better, Carddav support to sync cards with outside ? ;)
Carddav support is not likely but vCard export could definitely be added. We are planning an improvement of the export system at some point and we’ll be sure to include that.

Beyond vCard export feature, is it possible to make it accessible directly from any addressbook as "remote addressbook" (with something like basic HTTP authentication - I don't thing phones and addressbooks or calendars can set Authorization headers like the way we can access Kantree API).
This would allow to sync directly to phones or desktop addressbooks without "downloading the export" every week ;)
Best Regards and good luck for your crowdfunding campaign ;)
