Not trying to blow our own trumpet here, more set a context, but at Ensembl we're really keen to produce online help that's free and open for people to access wherever they might be. One of the ways we do this is a YouTube channel which is very popular. YouTube, however, is not accessible everywhere. We know that a lot of people access Ensembl from China, where YouTube is definitely banned, so we set up a YouKu channel for them, which is also pretty popular. However we are aware of a small number of countries, possibly where Ensembl is less popular but still, if there are people who want the stuff we should do our best to get it to them, where YouTube is also banned and we don't think a website entirely in Chinese is the best way forward for them. I don't think it's feasible to set up video streaming channels in all of these countries, but rather to find a way that we can broadcast to all of them. Does anybody know how we might do this? We're already considering SciVee and I've emailed them to ask if they have any censorship problems.
Did you ever contact YouTube about this? It might be possible to work with them to do some tagging for science videos for countries where only part of the contents is blocked because of copyright reasons, most notably Germany.
And about Youku, I asked a collaborator in Iran, who checked and found it is not available from there.
At least in the case of Germany, things will only get blocked if they contain music (blame GEMA), so that's an easy enough issue to get around.
