On the crowdfunding, it is the first paragraph:
1.500 € => e-inclusion and cloud: Thanks to you, we
will organise 5 workshops to initiate people victim of the digital
divide to Silex. For you, we will add new services to store your data
and to collaborate such as Github or Owncloud.
Thanks for your comment, actually, it is almost done, I think you can test both (webdav and github) in http://preprod.silex.me
