See a demo: > > http://html5-demos.appspot.com/static/a.download.html > The argument for having a peer to peer unreliable datagram channel has been two: 1) Minimal delay by direct peer-to-peer connection instead of going through a central server. This as you can't normally establish a websocket connection to a browser behind a NAT/FW. 2) Scalability by not requiring a server or having to handle the data flows at all on the server side. As an individual I think these arguments are good, and assuming we can find a reasonable solution that fulfills the requirements we should specify it.
