How to construct my multilayer mode? For LAN i use UDP server/client.

  But for internet UDP is useless i think.

I have in mind something like:

1. The host create SQL database and store the game data
2. The clients connect via TCP/IP and sent requests in that database to get current state of the game.

Or is there a better option for internet multilayer?

I ask as general question.

BTW i use Delphi.
