Cool WebRTC use case - PeerCDN

I hadn't heard of PeerCDN prior to reading about the acquisition on Disruptive Wireless and the STC blog, however I have to say I think the use case is pretty cool. Essentially they want to leverage WebRTC to augment existing content delivery methodologies by leveraging peer to peer connections as well as the more traditional star type distribution methods.

To me that demonstrates the power of WebRTC and the fact that there are so many business models and product ideas out there that no one has even thought of yet.
