I was tinkering with the new Chromecast add-on for Google Chrome that allows you to "Cast" your entire screen (similar to AirPlay mirroring). There is a hidden debug/dev section of the settings screen that revealed something interesting:
"Fixed DIAL device IPs". This seems to hint that there may be a manual bypass for L2 discovery coming in the future which I think would be a huge step forward. This advanced screen doesn't allow input yet (which is probably why it's hidden in the HTML).
