I don’t think we are installing anything into Emacs. Collab-mode, if ever 
completes, will be like any other Emacs package.

Also, since what ever protocol collab-mode uses will be limited to collab-mode 
itself, I don’t think the protocol is very interesting to discuss anyway.

I’ve thought about using public keys for authentication. Users would share 
their public keys through secure side-channel, then it’s easy to verify you are 
connecting to the person you think you are connecting to.

I also thought about adding OpenID support to the signaling server, such that 
the signaling server can endorse each user’s identify. Is is obviously more 
complicated, and requires the user to trust the signaling server.
