I've just been experimenting with ownCloud.org's open source files repository manager (http://owncloud.org). It's a simple, beautiful bit of software and supports various kinds of access and authentication. I've made a directory publicly accessible with some multimedia in it here: http://firstname.lastname@example.org/files/clientsync/commonobjects
I've connected it via WebDAV to a Moodle 2.3 installation without a hitch (There's details on Moodle.org forums about how to do this), and successfully used it to deploy a few resources in a course. It looks like it could be an answer to my issues with using Moodle 2.x's file manager API for XML driven learning interactions. I've yet to test out any SMIL or MPEG7 sequences... wish me luck!
Is anyone else using ownCloud with M2? Had any issues with it?
