peerflix.gifPeerflix, the online peer-to-peer (P2P) service that allows members to legally trade DVDs, said it has raised $8 million in venture backing.

The company, based in Menlo Park, said it has more than 100,000 DVDs for trade on its network.

The venture round was led by Battery Ventures, and Battery partner Roger Lee joins the board. Lee is the same guy who invested very early into Friendster — long before it reached the height of its buzz. So he knows how powerful network effects can be — but also how vigilantly a company needs to stay abreast of trends to avoid being eclipsed by others.

Here is our earlier stuff on Peerflix, written in March. Note that they’d already raised a first round back then, and they’d signaled that this latest second round was coming. So they are on track.
