MediaWiki can use open video - it is involved in wiki.mozilla.org

Stunning Jeremy Orem wrote an extension to MediaWiki , allowing the direct introduction of Open Video (i.e. <video> ), and exploited this feature on wiki.mozilla.org . Take a look at my demo page (you just type the usual HTML syntax into wiki markup), and then smoothly use the wiki to post your Mozilla videos. (Note: the wiki.mozilla.org has a thirty-two megabyte limit on the size of the uploaded file.)
