Yeah, something like that. For example when you're playing in multi and don't want people to wait until your 512 kbps connection finishes leeching this huge 20 MB map, but want to get video, too, even if later. Of course, you can run both downloads, but then you have to download mp3 and skin twice. And it also hurts your bandwith, peppy (okay, this argument is less convincing since there are mirrors).
This version might just be the video alone zipped up in .osz file. And it looks quite easy to implement since you already provide no-video version.
