I need this too, and will look into it.

@datakurre we just received a request to create a RSS tile for cover but I know there is already one in:

https://github.com/plone/plone.app.standardtiles/blob/master/plone/app/standardtiles/rss.py

and I don't want to duplicate code and efforts; can you give us a light on how we can reuse this tile, and probably others also?

if we can find a way to make tiles compatible it would benefit everybody at the end (#81).

Well, it's the Cover which adds a lot of behavior or tiles with IPersistentCoverTile interface. I'd guess it should be made sure that Cover adapts tiles explicitly into IPersistentCoverTile before accessing those methods in Python code. Then create an adapter for that interface for the RSSTile.
