It would be cool. I'm okay with seeing the powerpoints though, as those can sometimes have really excellent information.
If someone does upload it to youtube, PLEASE subtitle it using the youtube subtitle ability to load .SRT and other files. This allows the subtitles to be translated ON THE FLY to your native youtube language.
It (subtitling) takes forever to do, but the end result is worth it as everyone can view it.
For an example, please see my subtitled video here:
