Networking: Available Servers

Hello, I am choosing to make a multiplayer version of a game I’m in progress of making. And I’ve explored the Unity reference for Networking, so I can understand somewhat of what’s going on with the servers / clients.

I was just wondering if there are any free server sites that i could use along with a unity Mac Standalone Player? As in a site of somekind that allows free servers or something? or could you tell me if SmartFox Server is safe? it asked me for my admin password to make a change, and i’d think it wouldn’t have to make a change like that to install something?

The Unity Networking model is mainly designed for one player’s computer to be the server. The master server then provides basic server tracking. Is this not sufficient for you case?
