I'm developing a game that requires up to four iPhones or iPod Touch to connect each other to play in turns.

My question is, how can I accomplish this via GameKit. I've read that using client/server sessions is the way of doing it. But I can't find any examples that would illustrate this.

Is it really possible to do it, or there can only be two devices connected at a time.

I'd really appreciate if you all could help me with a code sample.

Thanks.
