This is mostly an issue for the image webserver, but of course for functionality to be provided by the mwEmbed videoplayer.
I was thinking that for the download option in the menu to be really useful, it should actually download (doesn't do that on Safari, just embeds in an empty window). I was thinking we could add a download option to the image webservers, that could be triggered by URL. It would set Content-Disposition HTTP header in the URL response with the option "attachment; filename=test.ogg" and that should force browsers to actually download the file.
