google app engine - Creating a channel for webRTC video chat -

i've been following html5rocks webrtc guide , have javascript set described, guide not clear on how receive channeltoken, roomkey, , user id. guide says,

"note values used in javascript, such room variable , token used openchannel(), provided google app engine app itself: take @ index.html template in repository see values added."

unfortunately link provided no , i'm left little information regarding essential step in process. guide isn't clear whether or not google app engine necessary component , don't see why should be. have searched web in attempt find more useful source, unsuccessful. took @ webrtc demo(https://apprtc.appspot[dot]com), no seeing channel information generated server side. feel should able make simple http request google server , run there. information regarding problem appreciated.

apologies: code example has been moved here.

(been meaning update article, haven't had chance...)

the apprtc.appspot example uses channel api on app engine signaling, there lots of other ways this. signaling mechanisms not defined webrtc spec. (note signaling, accomplished via signaling service, exchange of network , media metadata in order set webrtc 'call': actual data communicated directly between peers.)

we ran codelab @ google i/o, describes start finish how build video chat application uses socket.io on node.js signaling (it's simple!) might want try instead.
