So, I know that CF has STream, and Stream has matured very nicely! Kudos on bringing that encoding time down.
I also know that CF is in beta with an image service which looks to be really groovy.
Since you already have the encoding processes in place, how about a Live streaming feature product that allows a user to push to CF from a source or WebRTC, CF transcodes it, and creates a publishing point that can go on websites.
As of right now, we have to use Wowza or Red5, and although those products/services are very good, I feel that they cannot leverage the infrastructure that CF can.
