I am the author of Knowfox, a self-hosted knowledge management solution. I very much love your app and would love to use it, but I would hate to be forced to leave some 40k notes, many of them migrated from earlier uses of Drupal and Evernote, behind.
Also, I use Knowfox to collect bookmarks, do CRM, sync with Pocket, generate websites and presentation slides, all of which I would like to continue to do.
So, do you have or plan an open, synching API for Agenda?
Best,
