Roughly: | |||
* Monkeypatch setLocalDescription. When called: | |||
** POST new fingerprint to the room using "newpc" action | |||
* Monkeypatch setRemoteDescription. When called: | |||
*# Check list of fingerprints published by other person in the room | |||
*# If no match, perform a room GET to refresh information, and compare again | |||
*# If still no match, set a timer for 1 second; on expiry, try one more fetch and compare | |||
*# If still no match, error out the session and log an error to the server | |||
