   3   connect/disconnect with sid+name (ID not required); name slightly redundant but easier
   4 quand on arrive dans la partie, on poll les sids pour savoir qui est en ligne (ping)
   5 (éventuel échange lastate avec les connectés, pong ...etc)
   6 ensuite quand qqun se deco il suffit d'écouter "disconnect"
   7 pareil quand quelqu'un reco.
