I'm having a hard time to get a P2P image. I opened the demo in one window and opened a second one. After about ten refreshes I've got an image from a peer (presumably the other window as the shared counter went up by one). I repeated a bunch of times but it seems the rate at which images are served from a peer seems very low. Could you explain why? (I'm on Chrome 26.0.1410.43 m)

Other then that, sweet proof of concept.
