I remember that MediaWiki installation allowed the configuration that essentially permits the use of Commons files, albeit in that case, the file will be downloaded and cached in the Wiki's own server [1].
That being said, though the image wasn't hotlinked directly, they expressed concerns of DDOS and the possible costs the Foundation has to incur from each load (they even pointed out that it's "fair and reasonable" to point donation link to them).
I would be interested to see how the licensing issue will be handled, though. The photographer licensed this photo as GFDL/CC BY-SA 3.0 [2], and hotlinking may break the term of these licenses.
