2 event = "gameconnect" ...etc
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.
8 (c'est assez rudimentaire et écoute trop de messages, mais dans un premier temps...)
