My company Kontiki (http://www.kontiki.com http://www.kontiki.com) has been providing peer-to-peer solutions for a while now. We do require a client installation but that's not an issue in an enterprise environment (our target market) where central software distribution is the norm. Most importantly, an installed client allows us to overcome the HTML5 Web Storage limit of 5-10MB. You can't really store much video content with that limit in place.
