I'm doing a presentation/workshop this Sunday at the Toronto Anarchist Bookfair at around 3pm on using the FreedomBox with a RaspberryPi.
I decided that rather than hosting things like owncloud or other packages myself and giving others access to my own small centralized service that it's better to spread the knowledge of how to self-host "cloud" services.
The freedombox is great and raspberrypi 2, while not quite free hardware, has enough power that it can run all the services reasonably quickly. I was running Tor, Privoxy, IkiWiki, OpenVPN, Tiny Tiny RSS and other packages on it.
