I agree. We have been trying to scale our Wowza on EC2 setup for live video streaming, but after looking at our options it was about the same price to just go with a VDN like Edgecast that managed the server complexity for us. If Amazon could support live streaming through Cloudfront I think they could undercut the existing VDNs on pricing and have a big opportunity in that market.
