I am trying to a create a multiplayer gaming session manager. Such that a user can start a gaming session and wait for other players to join the session, the session starts when the desired number of players join the session. Is it possible to create a live session ?

I am thinking of creating a custom object which holds gaming session information and additionally a field to indicate for how much time a session should be active and status of that session. A new user comes and  creates that session. When another user comes while the session is active, he should be able to join. After sometime that session should expire.

Can anyone plz plz provide me a direction to move ahead ??

Thanks,

Falguni
