Where do I start to implement a massively-multiplayer game on the Iphone?
<p>I have a card game on the iphone and I really would like to take it to the next step by allowing players to interact with each other in real-time environment.</p>

<p>My questions:</p>

<ol>
<li>Do I need a web server ?</li>
<li>Is there a third party specifically for iphone multiplayer games that I can use to host the game?</li>
<li>I would probably need a database - what is the best solution?</li>
<li>Should Apple push notifications be considered ?   </li>
</ol>
