hi ryan,
as jose already suggested, you should implement the four 
"button-selected" states using a room attribute. assuming you already 
have a chat room functional, and you have an object registered for 
events from that room, you can call URoom.setAttributeOnServer() to set 
your attribute, and then implement URoomListener.onUpdateRoomAttribute() 
in your event-handling class to respond to changes in the attribute.

your attribute-setting code might look like this:
yourRoom.setAttributeOnServer("selectedButton", "3", true)

and your event-handling code might look like this:
public function onUpdateRoomAttribute (e:URoomEvent):Void {
   if (e.getChangedAttr().attrVal == "1") {
     // Display button-one-selected state
   }
   // ...etc
}

here's more info from the docs:

=====
setAttributeOnServer

public function setAttributeOnServer(attrName:String, attrValue:String, 
isShared:Boolean, isPersistent:Boolean, appendVal:Boolean):Void

Asks Unity to set an attribute for this room. An attribute is simply a 
named piece of information stored by the room on the server, much like a 
variable, with the added benefit that it can be automatically shared 
with all clients in the room. Room attributes are intended to store 
information about the room's environment, such as the highscore in a 
game room or perhaps the position of the furniture in a virtual house.

If setAttributeOnServer() is called with isShared set to true, then the 
attribute value is automatically propagated to all clients in the room 
on which the attribute is set. Clients can respond to the changing of a 
shared room attribute value via the 
URoomListener.onUpdateRoomAttribute() event. Clients can only set 
attributes on rooms they are in.
