[x] if we want to go with webxdc, we should find a consensus about upper/lowercase spelling. I would go all lowercase for now. ownCloud struggled for years (and is still struggling) to get everyone to write it "ownCloud".
[x] the title of the page is still Vitesse
[x] the video doesn't show webxdc, only sending a DC message to a non-DC-client
[x] the page still talks of apps instead of interactive content
