Using MUC for sending game moves does not seem complicated to me at
all. It seems like the obvious choice.
Why is it necessary for a room to have a master/validator? I do not
think this is necessary at all because any client which supports the
protocol must have validity checking built in (for non-spectator
person-to-person games). This would make it very obvious to a client
when someone is cheating.
If anything I think this game component should be an extension of MUC
to allow for some niceties, like avoiding cropping the history of a
game for new spectators arriving in the middle of a game.
I'm not saying that there isn't a need for a game-specific component,
I'm just stating that:
1) The protocol (and the clients) should not prevent the use of a
MUC for sending game moves. MUC should be a baseline.
2) If you need to create a custom protocol for game serving
components to distribute game moves, it should be a logical extension
of the MUC protocol.
Again, I refer you to sections 2.3 (Re-Use Existing Protocols) and
2.7 (Stay Flexible) of XEP-0134 <http://www.xmpp.org/extensions/
xep-0134.html>, Protocol Design Guidelines.
