Wikipedia youtube interface

When I was looking for a song on google today I noticed, that on the first two results there was the direct link to the according youtube video and one could watch it directly through a simple AJAX trick on the results page. Very „nice“ 😉 but what about Wikipedia? Couldn’t there be a link system, like the internal link system, which links directly and automatically to a youtube movie like [v:youtube] or such? Is there something like that?
