Using PHP Sockets as a "Relay"

I'm tryin开发者_如何学Pythong to create a left > php socket-server < right relation with php sockets.

Let's say that I have a server-daemon on the left side, like a vnc-server that connects to the socket-server.

On the right side I've got a client that want to connect to the left server-daemon, but it has to be done through the socket-server.

The server environment is a fully featured Linux or Mac OS X Server host with php5.3.

Any idéas?

Thanks / Trikks

Ended up building a solution in objective-c running as a daemon instead.
