Public sharing activity feed

I am trying to set up a solution for public users of our website to directly download our latest content release directly from OwnCloud (9.1.1).
In order to have an activity feed on my website, I'm using the RSS Feed option from the activity feed of a special "public" user.
The problem is that when a user of my website clicks on the link provided in the RSS Feed, it just tries to access the folder through a user, not through the public sharing, and as a result asks for authentication.

Would it be possible to either have a "special" public sharing activity feed (with RSS support) or be able to modify the current user's activity feed in order to have all the links point to shared links (maybe an option to display only publicly shared files/folder)?

Moved to the feature request category.
