As the title says, it is done and working very well over the Internet. I would like to share this HOWTO with everybody, perhaps we all can contribute a bit toward its perfection. What is the recommended location to post something like this?
HW: Banana PI, SDCard, USB Flash drive
SW: Bananian, LAMP, Owncloud, SSL, NTP
The idea is to have private storage, contacts, calendars and notes available on any of your (mobile) devices.
