You require that anyone sending presence to the room does so using
Presence Capabilities, and that the capability resolves to a feature
that the room requires. This would be a slight modification to MUC, but
the room configuration data form would have a "required client presence
features" and that would then be enforced.

Again, a slight change to MUC to allow the server in question to
announce configured features. Features would be on a per-game server
basis. You would also want to add Features into a room, so that you
could Discover just "Chess" rooms, or "Checkers" rooms.

I would probably use Voice. The only person with rights to actually
speak in the room (aka: Issue a Move) would be the referee. You would
sent moves to the moderator (which you can discover), and if the move is
valid then he would post it to the room. If the move is not valid, you
would get an error back.
