I might do something like this soon, I've been messing with a remote server management idea.
The only issue using torque to host the web server is that it can be flooded and lock the server up, or so I've heard.
I've had my friend spam a web server I hosted with Blockland and I didn't feel anything in-game, I was also spamming it too.
I might check out to see how websockets works, I was using an XMLHttp request and setting it as an interval whenever I had information that needed updating.
It works, but I believe websockets will work better for this.
