Participants of multiple rooms

[NathanRSmith]

Currently bb uses the session variable 'participant' to determine if a user is logged into a room which is set in 'JoinView'. What if a user wishes to have multiple rooms open in separate windows or in my case within the same Dashboard? Seems to me like there should a session object per participant per room and the room to be operated on should be passed in the request when a user leaves a room, sends a heartbeat, and sends a new room center (Join already passes the room name). Otherwise (I noticed) things like re-centering in one room will only affect the last room joined, not necessarily the room for which the center was set.
