There is one problem with enclosure, in that is limited to one  
enclosure per item. Backgrounds on art.gnome.org have several downloads  
per item, so this wouldn't be possible in RSS. It looks like with  
Atom's <link> element, this might be possible. Would be possible for  
your app to read an Atom feed instead?

Does anyone know more about Atom, and it's possible advantages or  
limitations?

I think we need the following parameters:

type = theme or background
category = sub category of theme or background (e.g. splash screen, or  
abstract backgrounds)
resolution = background specific resolution field
count = number of rows to return
order = descending or ascending
sort = date, name, rating, popularity

I think that would cover anything you might need.
