I think the streaming business is really interesting, I assume the reason Twitch (Amazon) is so successful is that they own their own infrastructure. Youtube is a competitor for the same reason.

Using Akamai/other CDNs is just crazy expensive, wonder what smashcast (formerly azubu and hitbox), Mixer (microsoft), AfreecaTV, and I assume there are some large chinese streaming sites use

Is this being used right now by Vimeo and Livestream?

I kind of get the use case, I wonder what the cost is like with traditional CDNs.
