What iPhone APIs are available for internet-based matchmaking games?
<p>I have a pretty basic challenge-based iPhone game, and I wanted to know what my options are for player discovery &amp; matchmaking. I may end up rolling my own server, but if I don't have to, even better.</p>

<p>So far, I've found <a href="http://openfeint.com" rel="nofollow">OpenFeint</a> and <a href="http://scoreloop.com" rel="nofollow">Scoreloop</a>, but I don't really care about the social part or discovering other games, I just want a simple system with matchmaking, win/loss, and global rankings. <a href="http://www.cocoslive.net/" rel="nofollow">CocosLive</a> has the global ranking part, but not the matchmaking.</p>

<p>Also just found <a href="http://www.jenkinssoftware.com/index.html" rel="nofollow">RakNet</a>.</p>

<p>Thanks.</p>
