Hi, Hadar here, Co-founder and CEO of Peer5. PeerCDN started at about the same time as Peer5 and was a competitor. Later it was acquired by Yahoo.

PeerCDN was a general purpose CDN, while Peer5 specializes in video. Feross, one of PeerCDN's founders and author of WebTorrent actually became my friend and we exchange ideas from time to time.
