Did some more developing on my concept testing game server. Rooms now have connectivity (Portals). The current testing map creates 4 rooms and links them to the starting lobby, users can move between rooms. This is in preparation for event propagation - sounds/actions/etc will be events that pass from location to connected locations, changing as they go.

The plan is that a clear sound in one room will be muffled if passing through a closed door, and become muffled after passing through multiple open doors. Visual events will become less detailed as they pass through (open) portals. Also line-of-sight will affect the events, so that sound becomes muffled faster going around corners, and visual events won't go around corners.
